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.

General description
Application
Insulin wird in vielen Kultursystemen mit Säugetierzellen als Wachstumsfaktor verwendet.
Biochem/physiol Actions
Zweikettige Polypeptidhormone, die durch die β-Zellen der Langerhans-Inseln produziert werden. Ihr Molekulargewicht ist ~5800 Da. Die α- und β-Ketten sind durch zwei Disulfidbrücken verbunden. Die α−Kette enthält eine intrakettige Disulfidbindung. Insulin reguliert die zelluläre Aufnahme, Nutzung und Speicherung von Glucose, Aminosäuren und Fettsäuren und hemmt den Abbau von Glycogen, Eiweiß und Fett.
Physical form
Pulver-0 °C; die Lösung ist bei 2 - 8 °C für 1 Jahr haltbar
Preparation Note
Zur Herstellung von 10 mg/ml Stammlösung 10 ml gesäuertes H2O (pH ≤2) zugeben, das durch Zugabe von Eisessig (ca. 0,1 ml) präpariert wurde.

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.

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.
