[DESCRIPTION]
Many research questions in ecology and evolution require balancing sampling strategies between their spatial (how many populations? on which geographical, environmental gradients?), temporal (diachronic approaches), and genomic (how many and which loci?) dimensions. High-throughput molecular biology protocols often offer very good genomic coverage, but this is often only achievable at the expense of other sampling dimensions. This has led to the development of targeted genotyping strategies for SNP locus sets, in addition to whole or reduced genome sequencing strategies. We here present an adaptation of a protocol developed by the University of Melbourne for genotyping rare variants in human oncology to non-model species for use in ecology and evolution. Hi-Plex is an amplicon sequencing technique (sensu Meek & Larson 2019) in which all loci are co-amplified in a multiplex reaction before Illumina or Ion-Torrent sequencing (we used Illumina). Intermediate steps include dual indexing of individual samples used for demultiplexing.

[BEFORE_START]
Select a set of SNP loci to include in your SNP panel. Prepare a fasta file with one 145bp sequence per locus. SNP loci can be selected from any genomic resource with information on polymorphism. If such resources do not exist, they can be generated from various protocols (see for instance Delord et al. 2018).
The number of samples to be genotyped should ideally be a multiple of 96
Choose a sequencing technology that allows reaching 100x read depth per locus per sample

[GUIDELINES]
The Hi-Plex protocol is adapted for population genetic studies using SNPs or microhaplotypes. It is an amplicon sequencing technique (sensu Meek & Larson 2019) in which all loci are co-amplified in a multiplex reaction before Illumina or Ion-Torrent sequencing (we used Illumina). Depending on the number of loci and samples, and given actual reagent and sequencing costs, multilocus genotypes at up to 400 loci can be obtained for about 10 to 15€ per sample.

2. Gene Specific Primers (GSP) preparation

GSP synthesis

Prepare a fasta file with 145bp sequences that will be used to design GSPs. Sequence names should contain the position and polymorphism of the targeted SNP.
An example of one such sequence is:

CGGGCCGGCCCGTCCAAAAATAGCAAGCAGAGTGAAATCCTCCACATTCTAAATGGCCACATGCACAAACAAGCAGTGTTTTCTTAAAGAGACCACTGCTCCCAGCTCACCCAGCAGCCTCTCACAGACAGTGGTGGGGGGGGGG

Send the file to Daniel Park (djp@unimelb.edu.au) and Bernie Pope (bjpope@unimelb.edu.au) for primer design.

Add the following common heels to forward and reverse specific primers:
Forward heel in 5'-3' : CTCTCTATGGGCAGTCGGTGATT
Reverse heel in 5'-3' : CTGCGTGTCTCCGACTCAG

Then, order GSPs in 96-well plates with a minimum yield of 10 nmol, purified using standard desalination with a purity of up to 70% to obtain 100 µL of 100-200 µM concentration in TE.

GSP pool preparation

Prepare 40 µM plates from each 100 or 200 µM GSP plate using 1X low TE (10 mM Tris pH8.0/0.1mM EDTA):
 

 Pool all forward and reverse GSPs.
First take 5 µL of each GSP-F and GSP-R at 40 µM and pool them by row in a 8-tube strip.
Then, pool the content of the strip into a 2 mL microcentrifuge tube. See diagram and table below.
Prepare as many aliquots as possible to avoid multiple freeze-thaw cycles.

TSITs preparation
Make a new plate diluted to 50 µM from each TSIT plate (TSIT_A and TSIT_P) at 100 or 200 µM in 100 µL/TSIT in TE: TSIT_A_50µM and TSIT_P_50µM.
       Ci µM         Cf µM         Vi µL         Vf         V TE            200         50         50         200         150            100         50         100         200         100      

Finally prepare 10 µM plates by mixing 2 by 2 TSIT_A with TSIT_P to obtain 9 plates of different combinations (plates are named TSIT_10µM_1 to TSIT_10µM_9).
As the TSIT_A are arranged columnwise in plate TSIT_A_50µM and TSIT_P are sorted rowise in plate TSIT_P_50µM, distribute 5µL of each column of TSIT_A and each row of TSIT_P in the 9 plates according to the table below.

4. Important informations before starting PCRs

Please read the GUIDELINES & WARNINGS to set up appropriate genotyping experiments. Make sure your number of samples is a multiple of 96 and the sequencing strategy you have chosen allows to reach 100X read depth for each sample at each locus. Note that replicating some samples can provide interesting information about genotyping quality (we run at least one set of 96 samples in triplicate for each new species or SNP panel we analyze).

Then,
prepare a PCR plate layout,
and determine the TSIT combinations that will be used for each sample/DNA plate. Make sure not to use the same TSIT plate twice in the same sequencing run. Each barcode combination must be unique.

For each PCR, we advise to report those informations in tables, for example:

6. Pooling PCR products
Centrifuge each PCR plate before remove sealing foil film.
on ice Prepare one 2mL tube per 96-well PCR plate. Use a multichannel pipette to transfer 20 µL of each PCR product to a tube strip. Combine all contents of the tube strip into a 2 mL microcentrifuge tube. For each 96-well plate, the final volume must reach 1,920 µL.
Store at 4 ˚C until the next step or at -20°C for longer storage.

7. Cleaning-up PCR pool on magnetic beads

  
Room temperature 
Ensure magnetic beads have been placed at room temperature for at least 30 minutes before starting the clean-up step. All steps are run twice to ensure optimal library preparation.
 
Bind target DNA fragment onto magnetic beads
To remove the smallest fragments and primer dimers, use a ratio 0.9/1 (beads/sample).
Transfer 960 µL of PCR products to a new 2 mL tube. Leave the remaining 960 µL at 4 ˚C until the end of the protocol or at -20 ˚C for longer term storage.
Add 864µL of presuspended magnetic beads (0.9x960µL=864µL).
Mix up and down 10 times with the pipette.
Incubate at room temperature for 5 min.
Place the tube in a magnetic rack and wait until all the beads are against the side of the tube. This could take a few minutes. 
Remove the supernatant without removing any bead.

Wash the beads with 85% ethanol
Add 500 µL of 85% ethanol to the beads and incubate at room temperature for 30 s.
Return the tube to the magnetic tube strip.
Remove the supernatant without removing any bead.
Repeat step 1 (second washing step).
Let beads dry on the magnetic rack for 5-15 min at room temperature.

Elute DNA
To elute DNA, remove the tubes from the magnetic rack. 
Add 70 µL of DNase/RNase free water and mix by pipetting up and down 10 times.
Incubate at room temperature for 1-5 min. 
Place the tube to the magnetic rack and wait for the beads to be against the magnetic strip.
Transfer the 70µl of water containing target DNA into a new 1.5 or 2 mL tube.

Bind eluted DNA onto magnetic beads
Add 63µL of presuspend magnetic beads (0.9x70µL=63µL) to the previously eluted DNA.
Mix up and down 10 times.
Incubate at room temperature for 5 min.

9. Size selection

Option 1: Size selection by electrophoresis in agarose gel

Agarose gel electrophoresis
Important: the electrophoresis comb must afford 55 µL loading volumes.
Prepare a 1.75% agarose gel using 1X TAE and ethidium bromide (EtBr). 
Add directly 55µL of each sample to a well (possible due to the use of the green buffer in previous PCR2 step)
Add 10 µL of the 50 bp ladder to at least one well (adapat to the number of samples or your gel size).
Run the gel at 100V for about 50-75 min to get more than 5 cm migration.

Size selection
Cut out an agarose gel band between 250-300 bp with a scalpel for each sample.
Weigh an empty 2 mL microcentrifuge tube. Then, add the gel slice to the tube and re-weigh.
Note the weigh of the agarose gel slice to adapt the correct volume of NTI buffer in next step.

DNA purification on silica column
Use the MN Nucleospin gel clean-up kit using the gel extraction protocol supplied by the manufacturer.
Prepare the NT3 and add the appropriate volume of 96-100% ethanol.
Adapt the volume of NTI buffer for each sample following : Vol. NTI = 2x agarose weight.
Elute with 2 x 25 µL of buffer NE (50 µL total).
Store at 4 ˚C.
The samples are now ready for the sequencing platform.

  

   
Option 2: Size selection by PippinTM prep

Bring each DNA sample from PCR2 up to 60μl with water.
Combine 60µl of DNA sample with 20μl of loading/marker mix (Marker L).
Mix samples thoroughly (vortex mixer). Briefly centrifuge to collect.
Remove 40μl of buffer from two "Sample Well" of the cassette, and load 40μl of sample into each well (2 wells per sample).
For each sample cut out band between 250-300 bp with “Range” option in PippinTM Prep software.
After migration, remove 40µl of sample from the two "Elution Module" of the cassette.

The Hi-Plex protocol we describe allows the co-amplification and subsequent sequencing of targeted SNP panels (up to 456 SNPs in our trials), and runs through different steps: the synthesis and preparation of gene specifics primers (GSPs) and adaptors (TSITs); a selective multiplex amplification of the SNP panel in a two-step PCR that allows building amplicons, the pooling of PCR products, a second PCR to increase the number of amplicon copies, interrupted with clean-up steps; quality control of the pooled libraries and their sequencing with custom sequencing primers. The sequencing-specific sequences included in the library constructions allow for both Illumina or IonTorrent sequencing but we only tested and thereafter show the protocol for Illumina Miseq sequencing.

Gene specific primers (GSPs) 
GSPs are forward and reverse oligos designed from target fragments of 145bp for each SNP. Each resulting Gene Specific Primer (GSP) is built from a target specific sequence and a common heel used to add individual index and sequencing oligos (TSIT).

Adaptors (TSITs)
TSITs are adaptors that consist of a complementary sequence to the GSP common heel, a barcode, and a specific sequence for Illumina sequencing (P5/P7) for a total of about 60 bp for each TSIT A and TSIT P. The use of a combination of this 2 barcodes allows the specific identification of the DNA samples.

Library preparation
The first PCR uses a high fidelity hot start taq polymerase and is made of two phases. In the first phase, a pool of all GSPs (50 µM) is used, to which TSIT adaptors are added for the second phase. The first PCR phase starts with 8 cycles with 2 successive hybridization temperatures (TM) at 58˚C and 60˚C, followed by 4 cycles at 58˚C. The second phase includes 4 cycles with a TM at 66˚C. The reaction is stopped by adding 100 mM EDTA at 72 ˚C and putting on ice.

The amplifications are pooled (the pooling unit is a 96-well plate) and purified using magnetic beads. Then, the second PCR is carried out using a high fidelity taq polymerase and the two Illumina's primers P5 and P7 at TM = 58 ˚C. The amplified fragments (250-300 bp) are size-selected by electrophoresis from an agarose gel colored with EtBr followed by extraction with a commercially available silica column or from an automatically size-selection system such as the PipinnTM prep. 

The use of EtBr is essential if size selection from agarose gel is performed. SybrSafe reagent, for example, generated a lot of non-specific amplicons. This suggests that SybrSafe does not allow for clean separation of migrated fragments on agarose gels.

    
Quality controls and sequencing
Each library is checked on a Fragment Analyzer™ to estimate the purity of the amplification products. Library concentration is then measured by KAPA qPCR on a LightCycler according to the manufacter protocol. All libraries are finally pooled together in equimolar quantities for sequencing performed on a Miseq platform (Illumina).

on ice PCR mix for one 96-well PCR plate
=> Keep all reagents, PCR plate on ice or cold cube during all process.
Prepare the PCR mix following the table below. The PCR mix can be used right away or stored on ice or at 4 ˚C for several hours.
Distribute 2 µL of DNA (or control) into each well – make sure to design a plate layout for the samples.
Distribute 21 µL of mix to each well.
Cover the PCR plate with foil sealing films and keep on ice until PCR running.

 

PCR cycles

 
To limit aspecific amplification, the PCR program requires a pre-heating step at 98 ˚C. Start the PCR program without inserting the plate. Store the plate on ice until the heating block on the machine has reached 98 ˚C. Then, insert the plate.
At the 1st step at 72°C forever, stop the run and open the thermocycler. Keep the PCR plate in the PCR machine at 72 ˚C.
Take the appropriate TSIT_10µM plates stored at 4 ˚C, centrifuge the plate, and carefully remove the sealing film.
Carefully remove the PCR plate sealing film.
Add 2.5 µL of each TSIT_10µM to each column of the PCR plate with a multichannel pipette. Mix by carefully pipetting up and down. Change tips for each column.
Close the PCR and TSIT_10µM plates with new sealing films. Restart the PCR program for the following steps.
At the final step at 72°C forever, stop the run and open the thermocycler. Keep the PCR plate in the PCR machine at 72 ˚C.
Take the EDTA 100mM in tube strips stored at 4°C, centrifuge the strip and carefully open up the caps.
Carefully remove the PCR plate sealing film.
Add 2.5 µL of EDTA 100mM to each column of the PCR plate with a multichannel pipette. Mix by carefully pipetting up and down. Change tips for each column.
Seal the plate with a new storage sealing foil film and put on ice immediately.
on ice Plates are placed directly on ice and stored at 4°C until the next steps.

SECTION: Quality and quantity control of libraries
11. Determine the quantity of DNA available for each library
Determine the DNA concentration of each library following the instruction of the KAPA Library Quantification Kit Illumina® Platforms (Roche Sequencing Solutions).
Based on concentrations measured for each library, make a final pool of equimolar concentrations.

This final pool is ready for sequencing following Illumina instructions.
