Application
- Cross-frontal mode: An alternative methodology for Taylor dispersion analysis of monomodal sample.: This research presents a novel methodology for Taylor dispersion analysis, which could be applied to the study of insulin dispersion and its implications in biochemical research (Gouyon et al., 2023).
Biochem/physiol Actions
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.

What can be used to make a solution of insulin?
1 answer-
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.

How can I store the insulin solution? How long?
1 answer-
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.

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