Insulin-Transferrin-Selenium (ITS-G) Select Supplement is an animal-origin-free (AOF) basal medium supplement that is used to reduce the amount of FBS needed to culture cells.

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/mL)
  • Transferrin (550.0 mg/mL)
  • Sodium selenite (0.67 mg/mL)

Frequently asked questions (FAQs)

What is the buffer composition of the various Insulin-Transferrin-Selenium (ITS) (100X) and Insulin-Transferrin-Selenium (ITS) Select (100X) supplements?

All ITS and ITS Select supplements are formulated in Earle's Balanced Salt Solution (EBSS).

What is the difference between Insulin-Transferrin-Selenium (ITS) (100X) and Insulin-Transferrin-Selenium (ITS) Select (100X) supplements?

ITS Select supplements are animal origin-free (AOF) versions of the ITS supplements offered by Thermo Fisher Scientific.

ITS Select supplements use recombinant versions of both proteins in the formulation: insulin and transferrin.

All other versions of ITS, those without the Select designation, utilize recombinant insulin and a human-derived holo transferrin.

What are the individual concentrations of insulin, transferrin, and selenium in the Insulin-Transferrin-Selenium (ITS) (100X) supplements?

All ITS and ITS Select supplements have the following concentrations of their components:

Insulin: 1.0 g/L
Transferrin: 0.55 g/L
Selenium: 0.00067 g/L

Can I store aliquots of Insulin-Transferrin-Selenium (ITS) (100X) supplements at -20 degrees C without compromising the integrity of the product?

We recommend storing all ITS and ITS Select supplements at 2-8 degrees C as there is a chance that the insulin will precipitate upon freezing and thawing.

Are all Insulin-Transferrin-Selenium (ITS) (100X) supplements offered by Thermo Fisher Scientific animal origin-free?

We offer both animal origin and animal origin-free versions of our ITS supplements. The animal origin-free product versions are referred to as ITS Select supplements.

Insulin-Transferrin-Selenium (ITS-G) (100X) (Cat. No. 41400045), Insulin-Transferrin-Selenium-Ethanolamine (ITS-X) (100X) (Cat. No. 51500056), and Insulin-Transferrin-Selenium-Sodium Pyruvate (ITS-A) (100X) (Cat. No. 51300044) are not animal origin-free.

Animal origin-free product versions are available for the ITS-G and ITS-X formulations: Insulin-Transferrin-Selenium (ITS-G) Select Supplement (100X) (Cat. No. A4000046501 and A4000046502) and Insulin-Transferrin-Selenium-Ethanolamine (ITS-X) Select Supplement (100X) (Cat. No. A4000046401 and Cat. No. A4000046402.
