General description

Recombinant Insulin, human, is produced in yeast and purified by standard chromatographic techniques. Insulin regulates blood glucose. In muscles and adipocytes it stimulates glucose intake and metabolism. It also controls the expression and various enzymes.

Specificity

Insulin, human, is active on most mammalian cells.

Application

Insulin shows a broad range of activities on a variety of somatic cells. Recombinant human insulin can be used to stimulate growth and proliferation of cultured cells and to investigate insulin activity on sensitive cells used in research studies. It is also a component of serum-free media formulations for most primary cells and cell lines.

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.

Quality

Endotoxin level: <0.1EU/μg (LAL-test)
Note: 1 EU corresponds to 0.1ng

Sequence

A-chain: 21 AS, B-chain: 30 AS, connected by two disulfide bridges
Two polypeptide chains (A-chain: 21 amino acids, B-chain: 30 amino acids, connected by two disulfide bridges) identical to natural, human insulin.

Unit Definition

EC50 definition: The concentration of human insulin that is required to support half-maximal stimulation of cell proliferation (MTT cleavage) with 3T3 (A31) cells.

Physical form

Lyophilizate from a hydrochloric acid solution (pH 2.3) (crystalline insulin)

Preparation Note

Working concentration: 1-10 μg/ml
Recommended concentration for serum-free cell culture is 1-10 μg/ml.
The concentration of insulin required for stimulation of cell growth in almost all cases is extraordinarily high compared with the physiological concentration. Insulin may be mimicking insulin-like growth factors (IGFs, somatomedins) for some cell lines, and high insulin concentrations may be necessary to occupy receptors which have a high affinity for IGFs and a lower affinity for insulin.
Working solution: Dissolve Insulin, human, recombinant (100 mg or 500 mg), in sterile, double-dist. water (final concentration: 10 mg/ml).
Storage conditions (working solution): -15 to -25 °C
The reconstituted, undiluted solution is stable at -15 to -25 °C.

Note: Avoid repeated freezing and thawing.

Reconstitution

Reconstitute in sterile double-distilled water (final concentration 10 mg/ml), further dilution with PBS (phosphate buffered saline) or medium containing 1 mg/ml (0.1%) BSA (bovine serum albumin) [or HSA (human serum albumin)], or 1 to 10% serum.
