General description
Medium supplement composed of albumin, insulin, transferrin, cytokines, a cholesterol source, other defined organic and inorganic compounds and fetal calf serum (final concentration: 0.5%).
HFCS contains human proteins. The raw material from which the human proteins were isolated, has been tested for the presence of Hepatitis B surface Antigen (HBsAg) and HIV-1/2 antibodies and found to be negative (according to current quality control procedures).
