Need the answers to all please :) 1) You recently purchased a new mitogen at 1mg/1ml (stock) and then prepared 1:100 dilutions as a working solution (tube A). The company also suggest verifying the optimal dilution for your experiment by doing serial (twofold) dilutions. Describe how you would prepare 500microliters of working solution (tube A). What volume of inhibitor will you add in microliter? 2) You would like to optimize the working concentration of the inhibitor, and therefore perform two-fold...
