Assay: Compound Primary Screening: A 96 well u-bottom plate was prepared by writing the experiment number, plate number, date and initials in the top right corner of the plate lid. With a sterile 300 ml reservoir, and 25 ml serological pipette, evaporation buffer media was pipetted into reservoir in 25 ml increments. Using the liquid handler, 150 ul of evaporation buffer media was pipetted from reservoir into rows A and H, and Columns 1 and 12 of the 96 well u-bottom plate. Cell cultures were counted to obtain the density of cells per ml, and the culture viability. The cell density information was used to obtain 1,000,000 cells from culture using a 5 mL serological pipette into an epi tube. The cell density information from the culture was used to calculate the number of cells and volume of media needed for the assay to seed 1250 cells in 130 ul of media per available culture well in the 96 well u-bottom plate. Rows B through F were used for cells (50 wells in total), with row G left for an empty media control. The calculation was overestimated by 10 mL to account for the dead volume in the 300 ml reservoir. Once the media volume was calculated, the appropriate volume of media was pipetted in 25 mL increments into the 250 mL bottle using a 25 mL serological pipette. The 250 ml bottle was capped tightly, and placed into a 37° C. water bath for 2 minutes. While the culture media was warming, 10 mL of fresh media was pipetted from the 500 mL culture media bottle into a sterile 25 mL reservoir. Using the Eppendorf multichannel pipette, 130 ul of media was pipetted from the 25 mL reservoir into row G of the 96 well u-bottom plate. Once the 250 mL bottle of media was warmed, the volume of culture needed was pipetted into the bottle, and mixed gently with a 25 mL serological pipette as to not create bubbles, and then the contents of the bottle were pipetted into a new 300 mL reservoir. Using the liquid handler, 130 ul of culture was pipetted from the 300 mL reservoir into rows B through F of the 96 well u-bottom plate. Once the culture was added, the plate was placed into a 37° C. incubator until the compound master plate was prepared for use.Two 96 well u-bottom plates were prepared by writing the master plate name in the upper right corner of the plate lid. Labeling one DMSO master and the other Media Master. The compounds of interest were obtained from the laboratory freezer, and placed into a 25 well storage box with a lid, and set the box aside. The compounds were vortexed after thawing but before use. Using an automatic multichannel pipette, 20 ul of 100% DMSO was pipetted into wells B3-B11 through G3-G11 of the DMSO master plate. For each compound on the master plate, 50 ul of the compound were pipetted in the appropriate well of row 2 (reference plate map to determine appropriate well). A serial dilution was prepared beginning by aspirating 20 ul from row 2 and mixing with row 3, repeating until row 11 was reached. Using the liquid handler, 194 ul of Daudi media was dispensed into wells B2-B11 through G2-G11 of the Media master plate. Using the liquid handler, 6 ul from the DMSO master plate was aspirated and dispensed into the media master plate, mixing 100 ul twice.Compounds from master plate were then added to the culture plate. The culture plates were removed from the incubator, and set inside the biosafety cabinet. Using a liquid handler, 20 ul from wells B2 to B11 through G2 to G11 of master plate were aspirated, and dispensed into wells B2 to B11 through G2 to G11 of culture plate. This set was continued with each culture plate. Once the culture plates acquired their 20 ul of compound dilutions, they were placed back into the incubator, until their reads on Day 7 of experiment.
