Description générale

At least the same specific activity (EC<sub>50</sub>) compared to the indicated standard is guaranteed.
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.

Spécificité

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.

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.

Qualité

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

Séquence

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.

Définition de l'unité

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

Forme physique

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

Notes préparatoires

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.
