Nettet5. jan. 2024 · To prepare 100 mL of a 10 mg/mL Insulin stock solution, aseptically mix 1.0 g of Insulin (Sigma Catalog No. 91077C) with 100 mL of Cell Culture grade water (ATCC® 30-2205 ™). Dissolve the Insulin in water by adjusting the pH to 2.0- 3.0 with dilute HCl (0.1 or 0.01N, depending on the volume of the insulin solution).
