This SDS-PAGE loading buffer has SDS (a denaturing detergent), β-mercaptoethanol (a reducing agent), Coomassie Blue (a dye), and glycerol. You will need to dilute your protein samples such that the final concentration of the loading buffer is 1x, meaning that you will add 5 parts of the protein sample for every 1 part of 6x buffer. Calculate how much of the 6x loading buffer you will need to add to each sample. Then, add the appropriate amount of 6x SDS-PAGE loading buffer to the samples. Store the samples in the -20°C freezer. What is the final concentration of glycerol in each of the samples?
