Gene Information

human ... INS(3630)

Application

Insulin human has been used:
  • in the culture medium needed for the adipogenesis of ASCs (adipose-derived stem cells)[1]
  • to study the effect of insulin in the young and aged brains of rats.[2]
  • to study the effect of insulin on the inflammatory actions of protease-activated receptor 2 (PAR2) using mice model.[3]

Biochem/physiol Actions

Regulates the cellular uptake, utilization, and storage of glucose, amino acids, and fatty acids and inhibits the breakdown of glycogen, protein, and fat.
Two-chain polypeptide hormone produced by the β-cells of pancreatic islets. Its molecular weight is ~5800 Da. The α and β chains are joined by two interchain disulfide bonds. The α chain contains an intrachain disulfide bond. Insulin regulates the cellular uptake, utilization, and storage of glucose, amino acids, and fatty acids and inhibits the breakdown of glycogen, protein, and fat.

Preparation Note

This product can be solubilized in 20 mg/mL of 0.01 M HCL. After solubilizing the material , a stock solution can be stored for long term storage at -20°C in single-use aliquots. Freeze-thaw cycles should be avoided.
