Goals
Procedure
(note that while there were the amounts measured out- the amount of LB added to the flasks was actually less due to loss of sample in transferring it from the weigh dish to the flask)
Using the formula M1V1=M2V2 The volume or amount of kanamycin that would need to go into each of the flasks was 50 μg/mL x 35mL ÷50,000 μg = .035mL Kanamycin.
Preparation of Tris Buffer
the desired concentration of the stock was .1 M tris and a total of 25mL of stock was made. 1 mol/ 1L x .025 L= .025 mol .025 mol x 121.14 grams/1 mol = 3.0285 grams of tris in 25mL of water * in actuality, 3.080 grams of tris was added.
(The tris and water were not combined with the AuNP/BSa solutions today)
