Transferrin is an indispensable component in body fluids. It is not only involved in iron transport and metabolism, respiration, cell proliferation and immune system regulation, but also can regulate iron ion balance and energy balance. And it has antibacterial and bactericidal function.
Sodium Selenite is a cofactor that provides glutathione peroxidase and other proteins and is used as an antioxidant in culture.
Originally used in combination with RPMI 1640 and Minimum Essential Medium (MEM), ITS-G solutions are now commonly used in combination with other basal medium to support multiple cell types in the presence of 2-4% FBS.
