Experiments

BioC

Jay, Sairah and Meenakshi worked on lab work this week on Thursday and Friday night

They cultured the Ava genes and the positive control pglo and negative, of “no plasmid.” Did 2 batches of ligation product: one at 16C-30 minutes/80C-20 minutes on 10/29/15 thurs, transformed right after. Batch #2: 4C/Overnight, transformed after 21 hours on 10/30/2015 friday.

* Neither batch has colonies

* find or order more NEB bio brick kit

CCL

State of the lab at CCL is holding back doing more experiments.  Rikke will be doing more organization.  Advertise that we will be doing a cleanup on Tuesday if folks can help out. Part of the lab should be useable by Wednesday

Need to make glycerine stock. Do a simple class on how to make basic 101 lab techniques like making glycerine stock - Wayne can teach (but needs a week notice)

-[https://www.addgene.org/plasmid-protocols/create-glycerol-stock/](https://www.google.com/url?q=https://www.addgene.org/plasmid-protocols/create-glycerol-stock/&sa=D&usg=AFQjCNHTwx0Of2iX3KkZf4V4CVyzY3oP0Q)

* need to revive the stock
* need to do the RCA (talk to eric about it)
* get plates and do a mini prep (if something grows can put on glycerine)

Email Wayne for a date to teach a short session at CCL on how to make glycerine stocks

(other classes needed, making media, pouring plates, making liquid cultures, basic bacterial culturing)  Rikee: liquid media, plate pouring, streaking

# Meeting 10/3/15

BioCurious: Maria, Jay H., David H., Sairah

Zoom: Advait, Adarsh, Audrey, Victoria, Kye, Milo,Meenakshi

CCL: Patrik

## iGEM recap

* We did well, poster looked good, got a bronze medal, missed things on the wiki (they formally check the boxes), gene design wasn’t on there, no page with colabs, weakest link was wiki)

* Judges liked it, didnt have a lot of questions,
* Easier for HS teams to put together funding and collab with a DIY lab
* Patrik wants to do an article for BioCoder about DIY labs experience with iGEM
* two meetings on Sat, discussion session about new tracks at iGEM (hardware, art, etc); large discussion on costs that not only will costs NOT go down might go down and might go to weed out weaker teams, don’t have a grant writer on staff, no discount to community labs), no formal process for grants for 3rd world countries etc.
* Alternative, join the Labs Program: program for labs to make biobricks and get parts $500/year - https://igem.org/Labs\_Program
* DIY Bio labs should set up something for themselves aimed for DIY BioLab open to anyone HS or smaller colleges, lower costs.  If a hackathon make it a week long to get something accomplished. Many different possibilities.
* South American groups are forming their own iGEM alternative - Maria is contact point
* For community involvement: ask Citizen Schools, which offers a lot of established tech/STEM after school programs for lower-income/minority students, to maybe start an after school DIYBio/Introduction to Synthetic Biology- that way, involving students who may never otherwise experience this exposures
* Marc Juul is working with new BioBricks Foundation push, a node system for automated freezer to let labs network who has parts, opportunity for a challenge in lab automation
* Putting together mailing list for people interested in developing educational outreach programs with local schools. Willam&Mary team at iGEM had beautiful 80-page curriculum of simple classes. See also http://www.citizenschools.org/
* WIll hand out certificate for igem participation at CCL and BIoC

## Reschedule meetings? Maria will send out a google poll

[Link for poll: http://goo.gl/forms/dr3Gacd862](https://www.google.com/url?q=http://goo.gl/forms/dr3Gacd862&sa=D&usg=AFQjCNGqEJqznWu5bYb8zGFjiUTh_XuxsA)

### Option 1: Stay on Saturday mornings

Maybe drop down to meeting every other week?

### Option 2: Move to Mondays, every other week

Alternating with with Real Vegan Cheese

### Option 3: Merge with Real Vegan Cheese meetings?

We have a good amount of overlap with the RVC team anyway.

### Option 4: any other time slots?

## DNA synthesis

* We may still be able to convince IDT to give us the remaining $1400 in DNA synthesis, but someone will need to negotiate with them - any volunteers?
* We have the Addgene plasmids, and the initial set of IDT genes - all native cyanobacterial sequence. That good enough? If anything, it should provide lots of room for improvement by Directed Evolution...

## Website

We haven't done a very good job at showing to the general public what this project is about. The iGEM wiki we threw together at the very last minute is missing some major pieces of information. The iGEM wikis do attract a lot of traffic, so now that the wikis are unfrozen we should either clean it up or link out to whatever else we'd like to be the "front page" for this project ([like we did for Vegan Cheese last year](https://www.google.com/url?q=https://2014.igem.org/Team:SF_Bay_Area_DIYbio&sa=D&usg=AFQjCNF9dZ5Bhy9lCi-cbvelX6MQaJA1Gg)). We made some great diagrams for the iGEM poster and presentation that we can easily reuse for a kickass website…

Team - Advait, Sairah, Maria, Patrik, Rikke, Milo

## Indiegogo

Extend deadline? Add materials from poster, presentation.

6 days for more funding

## What should be our end goal for this project?

1. A statistically significant improvement in UV absorption? In E.coli UV resistance?
2. A publishable result?

## Experiments

What is next? Are we ready to do a round of Directed Evolution?

Who/When/Where?

Next experimental work: At BioCurious; transformation of IDT genes

Regular work night at CCL on Wednesdays - Mention on Lab Night meetup description

Potentially doing lab work at BioC on Thursday nights led by Jay

Need to do RCA nicking, check in with Eric H.

## Experiments:

1. ### Mycosporine transformation into HB101

THIS AFTERNOON AT BIOCURIOUS, starting 1pm

2. ### UV spectrum of crude mycosporine methanol extract

Here's two protocols for extraction of MAAs from cyanobacteria for spectroscopic analysis. As you can see the first one is very simple: extract in 100% methanol in the fridge overnight, centrifuge, and take the supernatant:

[https://www.researchgate.net/publication/263709935\_Biochemical\_characterization\_of\_sunscreening\_mycosporine-like\_amino\_acids\_from\_two\_Nostoc\_species\_inhabiting\_diverse\_habitats](https://www.google.com/url?q=https://www.researchgate.net/publication/263709935_Biochemical_characterization_of_sunscreening_mycosporine-like_amino_acids_from_two_Nostoc_species_inhabiting_diverse_habitats&sa=D&usg=AFQjCNH0LOa_dGrRH3oGi2yEr6_IS2W7dg)

Cyanobacterial cells were harvested by centrifugation, and MAAs were extracted in 2 mL of 100% high-performance liquid chromatography (HPLC) grade methanol overnight at 4 °C. The methanol extracts were centrifuged at 10,000 rpm for 10 min, and the supernatant was subjected to spectroscopic analysis between 250- and 700-nm wavelengths, using a double-beam spectrophotometer (UV-Vis 2900, Hitachi, Japan).

[http://maxwellsci.com/print/crjbs/v3-165-171.pdf](https://www.google.com/url?q=http://maxwellsci.com/print/crjbs/v3-165-171.pdf&sa=D&usg=AFQjCNHJC6LwvnwyfVAUe8eusuc7bprHRg)

Extraction of 10 mg of dried Aulosira fertilissima in 2 mL 20% Methanol(gradient grade) at 45ºC for 2h . Centrifugation if necessary (10 min 10000 U). 1.5 mL of the supernatant was lyophilised. 2 mL 100 % Methanol was redissolved in the residue further vortexing followed by centrifugation was done. 1.5 mL of the supernatant was evaporated at 45ºC. 1.5 mL H2O was redissolving in the residue, again vortexing and centrifugation was done. Spectroscopic analysis of the supernatant was taken from 200 to 750 nm.

Mycosporine  like amino acid (MAAs) (Garcia pichelz et al., 1993)

Step 1. Took 10 mg fresh biomass and were suspended in 20 ml of methanol

              (20%)  and homogenized.

Step2. Covered all the test tubes with aluminium foil and were kept at 45℃ in

            water bath for 2hrs.

Step3. Centrifuged and filtered the supernatant through whatman filter paper

            (No.1).

Step4. The absorbance of filtrate were measured spectrophotometrically at many

           wavelengths (310, 320, 330, 332, 334 and 260).

E. coli cells may be even easier to extract, because cyanobacteria tend to have a stronger cell wall![](images/image00.gif)

3. ### Directed Evolution Round 1?

Patrik will start writing up a protocol

Everybody who has done research on Directed Evolution should help out digging up published protocols.

### 4. Domestication of gene clusters into IGEM plasmid

restriction digest and ligation reaction (Tuesday or Wednesday)

We need Pstl; did we get that in the biobrick cloning kit from NEB?

## Total Participation in iGEM:

102: on google group

igem registered: 14 (other), 16(student), 7 (instructors) - total 37

# Meeting 9/5/15 2 WEEKS LEFT!!!!

Attendees:

        BioCurious: Maria, Jay, James, Phil, Prag (biomedical research at Stanford), Sairah, Lawrence (CS), April, Audrey, David H.

        CCL: Kye, Megan, Patrik, Patrick, Tom, Maureen

        ZOOM: Advait, Adarsh, Shreya, Rikke, David, Victoria

## UV Hardware:

Drops in the 340nm and 390nm range according to spectra

## Experiments:

Rikke starting another kill curve experiment at 1pm at CCL

Jay: transformation in mutagenic strain successful; nothing grew in HB101 (including pGLO positive control).

Need to start doing experiments collecting UV absorption spectrum:

- Measure UV absorption spectrum of TSB (tryptic soy broth). As you heard from Rikke, there seems to be an issue with fluorescence and/or UVabsorption in the medium we've been using for the kill curve experiments.

- Measure E. coli UV absorption spectrum, with and without the pGlo plasmid. (a) in whole cell suspension (b) in cell lysate, (c) in crude protein extract. If we hope to be able to detect a change in UV absorption spectrum in GFP, how should we best measure the spectrum?

- Once we have a mycosporine producing strain, we'll need some way to measure its spectrum as well. Eventually, we'd like to separate the MAAs by HPLC, but just like with the GFP, we could generate a spectrum for a crude extract as well. Here's a few protocols for extracting the MAA-containing fraction with methanol:

[https://www.researchgate.net/publication/263709935\_Biochemical\_characterization\_of\_sunscreening\_mycosporine-like\_amino\_acids\_from\_two\_Nostoc\_species\_inhabiting\_diverse\_habitats](https://www.google.com/url?q=https://www.researchgate.net/publication/263709935_Biochemical_characterization_of_sunscreening_mycosporine-like_amino_acids_from_two_Nostoc_species_inhabiting_diverse_habitats&sa=D&usg=AFQjCNH0LOa_dGrRH3oGi2yEr6_IS2W7dg)

Cyanobacterial cells were harvested by centrifugation, and MAAs were extracted in 2 mL of 100% high-performance liquid chromatography (HPLC) grade methanol overnight at 4 °C. The methanol extracts were centrifuged at 10,000 rpm for 10 min, and the supernatant was subjected to spectroscopic analysis between 250- and 700-nm wavelengths, using a double-beam spectrophotometer (UV-Vis 2900, Hitachi, Japan).

## IDT Order:

Need to finalize gene order for Anabaena gene cluster - see [https://docs.google.com/document/d/1AVc2TPD71psi-JXjWkUTxp79HHXIEM2vP6k7G7RxbWE/edit?usp=sharing](https://www.google.com/url?q=https://docs.google.com/document/d/1AVc2TPD71psi-JXjWkUTxp79HHXIEM2vP6k7G7RxbWE/edit?usp%3Dsharing&sa=D&usg=AFQjCNEi_5UvMshIHfAGojmwaO-l2Latzw)

Jay and Patrik will coordinate on finalizing sequence; can also run by Eric Harness and Wayne

## Survey:

[https://docs.google.com/forms/d/19URbYIXXwWi9Hv4B7BM6-iEntHuiCIOcK3TGyA39sjI/viewform?usp=send\_form](https://www.google.com/url?q=https://docs.google.com/forms/d/19URbYIXXwWi9Hv4B7BM6-iEntHuiCIOcK3TGyA39sjI/viewform?usp%3Dsend_form&sa=D&usg=AFQjCNH5kM_Woa_q-4YrXKTFbiTw_YB81w)

* are you concerned about effect of sunscreens on your own health
* on the environment?
* difference between UVA, UVB
* environmental issues are mainly on coral reefs, not coastal environment. and mostly due to other compounds than PABA, TiO2
* would you wear sunscreen more if there were a more natural alternative?

Indiegogo Campaign:

Let’s put the fundraiser under CCL

Meeting 8/29/15 3 Weeks left!!

Attendees:

BioCurious: Maria, Jay, Audrey, April, Priyanka, Sairah, David H.

CCL: Rikke, Kye, Sean

        Zoom: David, Adarsh, Victoria, David M.

UV Hardware

Leave as is but UV exposure is not killing bacteria even at 1 hour of exposure, going to try moving closer to lights, right now we are at 8”

Problem with kill curve experiment: Some plates with high UV exposure have more growth than plate exposed to lower amounts of UV. In addition, GFP expression across plates are inconsistent.

potential hypotheses:

1. UV light is not close enough to kill majority of bacteria.
2. Bacteria is under stress due to UV irradiation and does not use pGLO plasmid as it doesn’t seem to provide benefit. Note that we are irradiating bacteria with a wide UV spectrum while GFP only absorbs a fraction of it.
3. The TSB media partially absorbs UV light, sheltering bacteria.

Need to get anabana transformed into ecoli onto plate and to CCL

Jay will send out operan again form addgene

At BioC today will miniprep out 5 of the plasmids from addgene today, wont do transformation today (need to get competent cells ready)

And then bring to CCL for kill curve checks

Assume we will do transformations at BioC on Tuesday @ approx 5:30pm to start will take about 3 hours

Patrik start cultures on monday and wednesday and experiments on tuesday and thrusday need to schedule someone to do cell counting within 24 not 48 hours afterwards at CCL

## UV Hardware

Made a frame to hold UV lamps

Spectroradiometer is working

Reptile lamp covers UVB really well

Supposedly 380nm LED array is really ~410nm - mostly blue visible light!

One of the nail curing lamps has nice broad peaks around 365nm and 400nm

Reptile lamps + nail curing lamp has reasonable match to solar UV spectrum

## Kill Curve Experiment

Coiled UV lamp in nail curing lamp may be burned out? Only designed to be on 1min at a time. Had to do without.

Need to do better job at normalizing initial cell density. pGlo overnight culture had far fewer cells to start with.

experiment notes: [https://docs.google.com/document/d/1Fio3o6M9dsEPUZZ7Ig5h4nN\_9p9mL4UdoYhWkxI7lF0/edit?usp=sharing](https://www.google.com/url?q=https://docs.google.com/document/d/1Fio3o6M9dsEPUZZ7Ig5h4nN_9p9mL4UdoYhWkxI7lF0/edit?usp%3Dsharing&sa=D&usg=AFQjCNH14yVYTSIn5HD58qzgLmxDPdKcIA)

Need to pour another stack of quartered plates (8 left, pour 20 more with LB agar)

At CCL this week approx 8pm to 11pm?

Monday - figure out UV setup and start overnight batch of liquid culture (Patrik, Sean)

Tuesday - Kill curve part 2 (any changes from the first run?)

Wednesday - someone make more culture

Thursday - Another run of Kill Curve

At BioCurious - need to follow up with Jay (Maria emailing)

Need to get our HPLC running - check with Jacob, Eric, Josiah

## Genes

8/21/15 Update from Jay (sorry can’t make today’s meeting)

The seven AddGene plasmids arrived.  I streaked two sets of plates, one for CCL and one for BioCurious.  FYI: Addgene used the Top10 E. coli cell line for delivering these plasmids.  They are all Kanamycin resistant for selection.  I will grow up some liquid cultures Saturday night and will be doing minipreps of the plasmids on Sunday afternoon starting around 3PM.  Anyone interested in joining this miniprep festival is welcome!!

I’m in progress designing a GFP-UV gene with His-tag and flanking sequences in the Bio Brick format.  As soon as the design is complete and checked we can order from IDT.        Anyone interested in helping out on this is certainly welcome.  Email me.

* Link to Genome Compiler:  [https://igem.genomecompiler.com/igem\_app](https://www.google.com/url?q=https://igem.genomecompiler.com/igem_app&sa=D&usg=AFQjCNGLSfg1bIzs8lLDYJRxy3lFYP4mdA)

All: what else are we ordering from IDT, and when?

* Has anyone looked at Jay’s gene cluster construct?  Have someone else review
* Need to order GFP with histags - Jay will design today in genome compiler folder

## Fundraising

* Indiegogo is ready we can launch today
* Lets launch today!

## Environmental/Ethical/Legal/Societal Issues (EELSI)

## Experiments update

See [http://bayareaigem.herokuapp.com/index.php?title=Notebook](https://www.google.com/url?q=http://bayareaigem.herokuapp.com/index.php?title%3DNotebook&sa=D&usg=AFQjCNHiHRGUEf0j1nBttHMCpF_piEzwNg)

1. pGLO transformation at BioCurious (Jay)

The transformation we did on Saturday was successful.  We got some transformants on plates 1B, 3B and 2B expressing GFP.  I attached images showing all the plates and the GFP glowing under UV (let me know if you need a higher res image).  Below is a table of the plate by plate outcomes.   We used pGLO plasmids from different sources and some were over a year old so we expected that not all would successfully transform.  Thanks to everyone who helped out on Saturday!!

I'll streak an HB101/pGLO plate for CCL.  I plan to do a miniprep to purify the pGLO plasmid on Thursday night starting around 7pm if anyone wants to participate. Patrik will be at Biocurious on Thursday night and he can pick up a plate with the transformed HB101 and some plasmid to take back to CCL.

Plate                        Observation

1                        Lawn         LA plate no ARA

1B                        > 20 colonies expressing GFP

2                        No growth

2B                        > 100 colonies expressing GFP

3                        ~ 6 colonies - no GFP (did not glow under UV)

3B                        > 20 colonies expressing GFP

4A                        No growth

4B                        Lawn        LA plate No ARA

5A                        No growth

5B                        No growth

6A                        No growth

6B                        No growth

7                        No growth

2. UV sources

See [Notes on UV Spectra](https://www.google.com/url?q=https://docs.google.com/document/d/1frmVyd8b8TmWgwaUV8lN5-0OlswaJP0t5B3H_hwRWGo/edit?usp%3Dsharing&sa=D&usg=AFQjCNEB3eJ43UpBA-jO90jCx-53OBTw4g) - all the hardware is documented there

3. UV kill curve experiments at CCL (Rikke)

Need to normalize bacterial cultures - need to get spectrophotometer online to calculate cell count based on optical density (OD)

Use drop spot plate method for plate counts - saves a lot on plates

Use 96 well plates and multipipetters to do dilutions

## Genes

Jay found the Anabaena genes available on plasmids at Addgene - $65 each!

[http://www.addgene.org/Christopher\_T\_Walsh/](https://www.google.com/url?q=http://www.addgene.org/Christopher_T_Walsh/&sa=D&usg=AFQjCNHf59FCFhdqqg6iZL9iYzc8mmYcwA)

Let’s order what we already know we want to get from IDT asap. No need to order everything at once.

* codon optimized Anabaena genes (with separate promoters / in separate biobricks?)
* Nostoc final enzyme
* GFPuv with strong promoter, strong RBS, transcriptional terminator

Need to decide which exact E.coli strain to use with RCA (especially whether or not it should be a RecA / DNA repair mutant!)

         DH5 alpha sequence [http://www.ncbi.nlm.nih.gov/bioproject/205928](https://www.google.com/url?q=http://www.ncbi.nlm.nih.gov/bioproject/205928&sa=D&usg=AFQjCNGnvD4boUwKWSYz9dRDD6czeo4kgg)

Fundraising

* Indiegogo editable [https://www.indiegogo.com/projects/biosunblock-looking-at-sunscreen/x/6697587#/story](https://www.google.com/url?q=https://www.indiegogo.com/projects/biosunblock-looking-at-sunscreen/x/6697587%23/story&sa=D&usg=AFQjCNEX6vGRRpYUNe7PuVfCttq4erREBA)
* Need to finalize

FYI regarding images for the Indiegogo campaign: Instead of buying stock photos, look for images on Google Images that are labeled for reuse: [http://screencast.com/t/bnrtTRvhBX](https://www.google.com/url?q=http://screencast.com/t/bnrtTRvhBX&sa=D&usg=AFQjCNHLn8ezxv0TLdft6lcCiT22Xq5k6w)

- may need to hack one of our UV-specs to accept external light

- Start doing kill curve expts asap, on wild type e coli & mutator strain.

Start doing experiments at CCL on UV on Wednesday

## Finalize IDT gene order

- Patrik can do codon optimization

- Which promoter & RBS to add? Or assemble everything from existing biobricks?

- Which flanking sequences do we need, for which assembly method?

Meeting 7/27/15

Attendees:

        BioCurious: Eric H., Maria T. Chavez, Patrik, Eric A, Adarash, James, Rikke, Victoria, Dmitry, Jay, Erik I, Greg, Shreya, Michael, Samera, David, Meekakshi, Johan

Eric’s talk on RCA/RCR - Rolling circle amplification, Rolling circle replication

A way for viruses to replicate their DNA, a compact way to replicate their dna needing only 1 strand of DNA.  Uses enzyme phi 29.  A way to produce lots of DNA at a low temperature.

Need a circle, need an initiation point (a single stranded circle), 529 will initiate this at the lesion in a double stranded DNA. Phi 29 has a fidelity for doing this that is unreplicated so far from bascillius setellus (???)

RCA is not old technology, it was developed to make copies, for Sanger sequencing.  To make a lot of copies of something that is a replication.  Make a copy of a whole circle, strand replace and start again making a new circle of DNA.  Pic of process - https://en.wikipedia.org/wiki/Rolling\_circle\_replication.

For our process is to NOT use phi 29 to introduce mutagenesis.

DNB is a DNA nanoball.

Eric today took M13 and put a nick in it to use it today.  MB-BSM1 is an asymmetric cutting enzyme and will make a nick in the DNA either top strand (MB is the bottom strand).

Eric will post Protocol used for tonight.

## Gene designs

Anyone to contact Minnesota 2012 team (Jay)

Link to Minnesota 2012 iGEM Team UV-Protective Compounds : [https://2012.igem.org/Team:Minnesota/Project/UV\_Absorption](https://www.google.com/url?q=https://2012.igem.org/Team:Minnesota/Project/UV_Absorption&sa=D&usg=AFQjCNGaWgPyoDhZPaZikoLmDodMJ_im4g)

Need to finalize gene designs, including any flanking sequences

Milo, Jay, Patrik

Look into possible DNA assembly methods:

        Gibson

        Golden Gate

        Golden Braid

        Infusion Cloning - Clonetech

OTHER GENES:

* UV sensitive promoters? (see also [SulAp](https://www.google.com/url?q=http://parts.igem.org/wiki/index.php?title%3DPart:BBa_K518010&sa=D&usg=AFQjCNEl43KgE8jqh_KftRbXXzLi84aU9Q))
* reporter genes?

## UV spectra and hardware

mycosporines absorb in UVB UVA (334nm)

GFP absorbs in UVA (395nm)

we have various UV illuminators (320nm, 365nm) - copy out some model numbers, and look up spectrum

        Stratagene crosslinker

More research on killing E. coli with UVA, UVB, sunlight - what doses at what wavelengths

* Rikke, Patrik

UV Sources:

* At Biocurious: “Strategene crosslinker” - has replaceable / swappable UV bulbs, so will need to know what type of bulb is in there to determine radiation specs

* Actual crosslinking is usually done with a very short-wave, very narrow-band UVC bulb (254nm), which would not be suitable for our purposes
* Manual says it also has 302nm Midrange (UVB) bulbs (# 34-0042-01) and 365 nm Longwave (UVA) bulbs (# 34-0006-01),

UVP Cross linker  Midrange 302nm UV:40 watts

        - Need to build a budget, each subgroup to let us know a very general cost, and what materials we need ordered (so we can look into getting supplies donated)

Which genes do we need to order?

[https://2015.igem.org/Sponsors/IDT](https://www.google.com/url?q=https://2015.igem.org/Sponsors/IDT&sa=D&usg=AFQjCNFY4milYReUw_JAf7FY1mcxD4rSGw)        \*Teams will receive value equivalent to twenty 1000 bp gBlocks Gene Fragments in their local currency. Promotion expires September 24, 2015.

1. Shinorine pathway:

* mycosporine-glycine pathway from Minnesota 2012 team is NOT available; need to reorder! Anabaena variabilis Ava\_3855 to 3858

* We could also order Nostoc punctiforme NpF5597 to 5600 as an alternative, and codon optimized versions of both

* The Minnesota team could not get Ava\_3855 to work, but we've identified 9 other enzymes that can do the final step in the pathway

2. pABA biosynthesis

* BBa\_K137055 from Caltech 2008 (promoter +  RBS + PabA; IN 2015 IGEM KIT!)

* BBa\_K909014 from Zurich 2012 (P + RBS + PabB + RBS + PabA + term; IN IGEM 2015!)

* express antisense RNA for pABA consuming enzyme?

3. GFP

* What is the most favorite GFP biobrick?

4. UV sensitive promoters

* BBa\_J22106 RecA SOS promoter (in stock, not on distribution)

* What else?

5. Any reporter genes (other than GFP!?

Need someone to look into UV light spectrums - could look into what UV lights we should be using (LED's that are mostly UVA, broad spectrum UV light) What spectrum, what hardware, what level of elimination to kill e-coli, what has been used by other labs - \*\* Rikke

Directed Evolution Update -

ELSI - April and Audrey will dig more into the issues around PABA

TODO:

        - directed evolution look up $ estimates for experiments w mutator strain vs RCA

        - come up with concrete list of genes to order from IDT

        - transfer all notes to Wiki:[http://bayareaigem.herokuapp.com/](https://www.google.com/url?q=http://bayareaigem.herokuapp.com/&sa=D&usg=AFQjCNGlkmaG_PzoltN8fGQo6uQoUdvP9Q)
