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
Hormona polipeptídica bicatenaria producida por las células β de los islotes pancreáticos. Su peso molecular es de ~ 5800 Da) Las cadenas α y β se unen por dos enlaces disulfuro intercatenarios. La cadena α contiene un puente disulfuro intracatenario. La insulina regula la captación, utilización y almacenamiento celulares de glucosa, aminoácidos y ácidos grasos, e inhibe la hidrólisis de glucógeno, proteínas y grasas.

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.
