General description
In Zellkulturmedien hat es eine biologische Halbwertszeit von ca. 19 Minuten. Es handelt sich um ein starkes Methylierungsmittel, das in vitro mit der DNA interagiert und methylierte Purine produziert. Da STZ besonders toxisch für die insulinproduzierenden Betazellen des Pankreas bei Säugetieren ist, kann es den Glukosestoffwechsel beeinträchtigen. Außerdem ist es ein wirksames Antibiotikum gegen gramnegative Bakterien. Es hemmt die DNA-Synthese in Mikroorganismen und Säugetierzellen durch Alkylierung und Vernetzung der DNA-Stränge und beeinflusst alle Phasen des Zellzyklus von Säugetieren. STZ gilt beim Menschen als mutagen, krebserregend und möglicherweise teratogen. Es ist zytotoxisch für neuroendokrine Tumorzelllinien, die den GLUT2-Glucosetransporter exprimieren.

Can I prepare an STZ solution using 1X PBS with this product? If so, could you provide the appropriate concentration?
1 answer-
This product, Streptozocin, has not been tested for solubility in phosphate-buffered saline. However, other sources report solubility in phosphate-buffered saline at pH 7.2, approximately 5 mg/mL. It is not recommended to use phosphate-buffered saline as a solvent since it has not been tested. The decision on the solvent should be made by the end user. This product should be dissolved in water at 50 mg/mL to produce a light yellow solution, which can range from clear to slightly hazy. A 20 mM citrate buffer at pH 4.5 is recommended for optimal solution stability. The product should be used immediately after solubilization, as storage in solution form is not recommended due to instability.

Can Product S0130, Streptozocin, be used to induce diabetes? What concentration should be used?
1 answer-
We do not test Streptozocin, Product No. S0130 for biological activity. We recommend screening lots for biological activity. An intravenous injection of streptozocin into rats at a dose of 65 mg/kg body weight to induce diabetes has been reported by Burcelin R. et al. in Biochem. J., 291, 109-113 (1993).

How should I store Product S0130, Streptozocin, upon receipt?
1 answer-
Streptozocin should be stored at -20 degrees C with desiccation. The desiccant is to prevent moisture uptake which can shorten shelf-life.

How do I store solutions of Product S0130, Streptozocin?
1 answer-
Aqueous solutions rapidly undergo mutarotation to an equilibrium mixture of alpha- and beta-anomers. Maximum solution stability is at pH 4, with stability decreasing rapidly at higher or lower pH. Freshly prepared solutions are clear and have a light straw color. On standing, they take on a yellow to brown color and effervesce, indicating decomposition. Solutions should be prepared just before use, since the product is unstable.
