- Write down a comparison of the sizes of the untreated Allium cepa cell and the colchicine-treated Allium cepa cell.The total number of cells in a culture is counted using the trypan blue exclusion assay and is found to be 6.8 x 106 cells/ml. Each well in a 6 well plate requires 2 x 105 cells. How should the solution be diluted so that 1ml can be added to each well?You need to prepare medium for your culture cells. Your salt solution is supplied at a 10X concentration but needs to be 2X for use. You also need to add fetal bovine serum for a final concentration of 8%. What would you add of each for the correct final concentrations in 5 L of media?
