Question
(30 points) Your colleague in the laboratory was able to collect all his raw data from a growth curve on iela S3 cell line, but had to leave unexpectedly and has asked you to perform cell calculations to your professor. This what your colleague did: he seeded cells into a 24-well plate (allows for licate sampling and it is much easier to handle one 24-well plate rather than 24 flasks), and on each the days indicated in the table on the following page, trypsinized and counted live/dead cells from three individual wells to allow for statistical accuracy. The information in the data table includes: day counted, media volume, dilutions, and number of live and dead cells counted (these numbers the average count from the three wells counted each day) with a Fuchs-Rosenthal need to: Perform all necessary calculations to determine cell number (in this case cells/ml equals total cell number) Record of cell counts Please note that these counts have all been done with Trypan Blue. Therefore, all cultures have been diluted two-fold (equal volume of cell suspension + equal volume of Trypan Blue). Take this into account when determining cell number. Any dilution listed in table is an additional dilution. Live and dead cells listed below represent the total number of cells in 5 large (1 mm) counting squares using a Fuchs-Rosenthal hemocytometer Day HemoTotal PBSLiveDead cytomcter Volume Dilution Cells mi Viability(live cells only) xi0 FuchsExplanation / Answer
Per cent viability is total cells/live cells *100
For example: 25+3/25 = 28/25 = 1.12 =112%
In an experiment the result that is above 100% is considered to be 100% only
Cells/ml= total cells counted*dilution factor*10,000 cells/ml/no. Of squares
