Aplicação

Insulin is used as a growth factor in many mammalian cell culture systems.
  • Insulin from bovine pancreas has been used for the differentiation of MSCs (mesenchymal stem cells) to adipocytes.
  • It has been used for culturing of various cells.
  • It has also been used to study insulin-mediated inhibition of the HMGCS2 (3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) synthase) gene.

Ações bioquímicas/fisiológicas

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 can be used to make a solution of insulin?

    Insulin is soluble in dilute acids and alkalis. The solubility of insulin is tested at 2 mg/mL in water (acidified to pH 2 with hydrochloric acid). One can also use 1 mL of water acidified to pH 2 with 10 μL of glacial acetic acid to dissolve 2 mg of insulin. A 10 mg/mL solution of bovine insulin in 25 mM HEPES at pH 8.2 is offered as Product No. I0516.

  4. How can I store the insulin solution?  How long?

    The USP recommends that solutions of insulin be stored at 2-8°C. It is not recommended to freeze solutions of insulin, as it can aggregate. Sterile solutions should be stable for at least 1 year at 2-8°C.

  5. What is the amino acid sequence for Product I6634, Insulin from bovine pancreas?

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

  6. How many units of insulin are present in my vial of Product I6634, Insulin from bovine pancreas?

    Product No. I6634 has a specification of not less than 27 USP units/mg.  The exact value for the product received can be found the on lot-specific Certificate of Analysis.

  7. 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.
