Bovine Insulin is a two-chain polypeptide hormone produced in vivo in the pancreatic β cells and it is the most studied hormone. Insulin regulates glucose uptake into muscle and fat cells by recruiting membrane glucose transporter Glut-4 to cell surface. Understanding how insulin regulates the movement of Glut-4 will lead to the development of new therapy to treat type II diabetes. Insulin also influences other body functions, such as vascular compliance and cognition. Insulin enhances learning and memory once it enters human brain and benefits verbal memory in particular.
Bovine Insulin has often been used as growth supplement in culturing cells at the concentration ranging from 1 to 10 micrograms per milliliter of medium. The amino acid sequence of insulin is extremely well preserved. Bovine insulin differs from human insulin in only three amino acid residues, that is similar enough to be clinically effective in humans.

Mix bovine insulin gently to make a homogeneous solution. Sterilize Bovine Insulin Stock Solution by filtering 10 ml through a syringe filter (0.2 μm pore size) and filtering 100ml through a 100ml filter unit (0.2 μm pore size). Aliquot single use aliquots in sterile vials as stock solution.
Store stock vials of bovine insulin at -20°C in a non frost-free freeze. Do not thaw and refreeze insulin. Store thawed insulin at 4°C.
