Application

Insulin solution from bovine pancreas has been used:
  • to study the effect of exogenous insulin on plasma concentrations of glucose, insulin, insulin-like growth factor I (IGF-I), and progesterone (P4) in pubertal beef heifers
  • to study the insulin responsiveness of the placenta during pregnancy complications using primary human trophoblast cells and placental villous explants
  • to study the effect of insulin receptor signaling dendritic spine density in neonatal mouse hippocampal neurons in vitro

Biochem/physiol Actions

Insulin is a major glucose-lowering hormone, insufficiency of which causes hyperglycemia observed in type 2 diabetes.
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.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. What is the comparison between International Units (IU) and USP units for insulin?

    The international unit (IU) of insulin is based on the International Standard Preparation of Bioassay (1958). The standard preparation is a mixture of 52% bovine and 48% porcine insulin, containing 24 units/mg. Reference: Martindale: The Extra Pharmacopoeia, 29th ed., p. 392. High purity bovine pancreatic insulin typically assays at approximately 27 USP units per mg. So the IU and USP unit are not identical, but they are approximately 1:1.

  3. What is the amino acid sequence for insulin?

    The sequence and structure of insulin can be found on the product information sheet (under Documents, above).

  4. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  5. How many units/mg am I getting in Product I0516, Insulin solution?

    This solution is made using insulin Product No. I5500.  The potency specification for the I5500 is not less than 27 USP units/mg.  However, we do not test for potency of the final product of this solution.  It is possible some activity is lost during the manufacturing process.

  6. What is the molarity of Product I0516, Insulin solution?

    Product No. I0516 is a 10 mg/mL solution of bovine insulin (MW 5733.5). The molarity is 1.7 μmol/mL or 1.7 mM.
