Insulin has low solubility at neutral pH. It can be solubilized at 1-10 mg/mL in dilute acetic (1%) or hydrochloric acid, pH 2-3. Insulin can also be solubilized in 125 mM NaHCO3.15 However, alkaline stock solutions are not recommended since high pH increases the rate of deamidation and aggregation.

Application
L'insuline est utilisée comme facteur de croissance dans de nombreux systèmes de culture de cellules de mammifères.
Actions biochimiques/physiologiques
Hormone polypeptidique à deux chaînes produite par les cellules β des îlots de Langerhans. Son poids moléculaire est d′environ 5 800 Da. Les chaînes α et β sont reliées par deux ponts disulfure interchaînes. La chaîne α contient un pont disulfure intrachaîne. L′insuline régule l′absorption, l′utilisation et le stockage par les cellules du glucose, des acides aminés et des acides gras et inhibe la dégradation du glycogène, des protéines et des graisses.

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.

How many units of insulin are present in one vial of Product I1882, Insulin from bovine pancreas?
1 answer-
Product No. I1882 has a potency specification of not less than 2520 USP units per vial. For a vial that contains (nominally) 100 mg, that works out to 25.2 USP units/mg. The potency in terms of units per vial can be found the on lot-specific Certificate of Analysis.

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.
