7) You will use about 1 ml of the following buffer every day in the lab so you decide to make a 5X master mix that will last for a year. List the stock solutions you will make and how you will make the stocks (also how much). Then list how you will dilute them to make the 5X master mix (and how much). We don't want to waste materials.
