Gibco™ Insulin-Transferrin-Selenium (ITS-G) Select Supplement (100X)

Gibco Insulin-Transferrin-Selenium (ITS-G) Select Supplement is an animal origin-free (AOF) basal medium supplement. The insulin and transferrin in the ITS-G Select formulation are produced in non-mammalian recombinant expression systems.

ITS-G is used as a basal medium supplement to reduce the amount of fetal bovine serum (FBS) needed to culture cells. Originally used with RPMI 1640 and Minimum Essential Medium (MEM), ITS-G is now routinely used with other basal media to support a wide variety of cell types in the presence of 2–4% FBS.

Insulin promotes glucose and amino acid uptake, lipogenesis, intracellular transport, and the synthesis of proteins and nucleic acids. Transferrin is an iron carrier and may also help reduce toxic levels of oxygen radicals and peroxide. Selenium, as sodium selenite, is a co-factor for glutathione peroxidase and other proteins and is used as an antioxidant in media.

The product formulation contains the following components:

• Insulin (1000.0 mg/L)
• Transferrin (550.0 mg/L)
• Sodium selenite (0.67 mg/L)
