Insulin-Transferrin-Selenium-Pyruvate Sodium Supplement (ITS-A) 100× Animal Origin-free

Sterilizing method: Filter sterilizing Insulin (INS) is a double-stranded form of polypeptide hormone (α, β) secreted by pancreatic islet beta cells, which is the only known hormone in the body to reduce blood sugar and promote the synthesis of glycogen, fat and protein at the same time. Transferrin is an indispensable component in body fluids, which not only participates in iron transport and metabolism, respiration, cell proliferation and immune system regulation, but also regulates iron ion balance and energy balance, and has antibacterial and bactericidal protection function. Selenium, provided as Sodium Selenite, is a cofactor of glutathione peroxidase and other proteins and is used as an antioxidant in media. Initially used in combination with RPMI 1640 and Minimum Essential Medium (MEM), ITS-G solutions are now commonly used in combination with other base medium to support multiple cell types in the presence of 2-4% FBS. ITS is formulated in Earle Balanced Salt Solution (EBSS). Beijing Solebol Technology Co. , Ltd. offers three different ITS: ITS-G(I3502) for general use, ITS-A(I3501) for adherent cell culture, and ITS-X(I3500) for cell types that require aminoethanol, such as bronchial epithelial cells.
