The complete formulation is available.

Using McCoy’s 5A (modified) Medium
Dr. Thomas McCoy originally formulated McCoy’s 5A medium as a modification of Basal Medium 5A. Unlike other media, McCoy’s 5A contains the reducing agent glutathione, bacto-peptone, and a high level of glucose. This product also includes Dr. Hsu’s addition of Hanks’ salts to enable use outside a CO₂ incubator. McCoy’s 5A (modified) Medium requires serum supplementation, commonly with 10% Fetal Bovine Serum (FBS). McCoy’s 5A (modified) Medium uses a sodium bicarbonate buffer system (2.2 g/L), and therefore requires a 5–10% CO₂ environment to maintain physiological pH.
