InVitria’s ITS, ITSE, and ITSE+A Animal-Free are recombinant, blood-free cell culture media supplements used to optimize cell growth. For optimal proliferation and performance, cells cultured must be supplied with a critical proteins and components:Insulin: promotes uptake of glucose and amino acids, facilitating cellular signalingTransferrin: delivers intracellular iron via the transferrin receptor, drives cellular respiration, chelates free iron, and reduces generation of cytotoxic free radicals and peroxideSelenium: required for the activity of antioxidant enzymes such as glutathione peroxidase and thioredoxin reductaseEthanolamine: phospholipid precursor that improves the performance of cells in serum-free media and is required for the growth of certain cell typesAlbumin: binds, transports, and delivers ions, fatty acids, vitamins, hormones, small-molecule drugs, and toxins; regulates serum pH and osmotic pressure; and provides antioxidant activityMade in the USA.
