Product Description

ITSE Animal-Free is a recombinant insulin and transferrin cell culture media supplement that is made in the USA and is animal component free. It is commonly used to reduce or remove fetal bovine serum. ITSE Animal-Free is unique because it uses recombinant technology, which allows for consistent results. ITSE Animal-Free provides all these benefits and is more cost-effective than traditional insulin and transferrin supplements.

What customers are saying about ITSE Animal-Free:

"InVitria's ITSE Animal-Free works well, and better than our alternative product from another supplier."

Insulin, transferrin, selenium and ethanolamine are typically required for optimal cell growth in serum-free media. Ethanolamine is a phospholipid precursor that improves the performance of cells in serum-free media and is required for the growth of some cell types. Insulin has cell signaling functions and promotes the uptake of glucose and amino acids. Transferrin is a universal source of iron for cells that is non-toxic carrier of iron and reduces the generation of toxic free-radicals and peroxide. Selenium is required for the activity of glutathione peroxidase, thioredoxin reductase, and other antioxidant enzymes.

Cell Culture Media Comparisons

Cell culture media supplement comparison chart comparing ITSE Animal Free to other commercial ITSE

Vero cells were grown over four days in DMEM/F12 media supplemented with InVitria's ITSE Animal-Free and another commercial ITSE. There is no significant difference between the performance cells grown in media supplemented with ITSE Animal-Free and cells grown in another commercial ITSE. Cells were grown in triplicate 1 mL static cultures, and were seeded at 1.2x104 cells/well.
