General description

Streptozocin or streptozotocin, is obtained from Streptomyces achromogenes. Streptozotocin, a glucosamine-nitrosourea, is a DNA alkylating agent that enters cells exclusively via the GLUT2 glucose transport protein. Streptozocin, a diabetagen, is especially toxic to pancreatic islet insulin-producing β-cells. It is toxic to GLUT2 positive neuroendocrine tumor cells.


Streptozocin or streptozotocin is used to induce type 1 diabetes for medical research.

Biochem/physiol Actions

An N-nitroso-containing compound that acts as a nitric oxide donor in pancreatic islets; induces death of insulin-secreting cells, producing an animal model of diabetes. Potent DNA methylating agent that induces chromosomal breakage. Cytotoxic to neuroendocrine tumor cell lines that express the GLUT2 glucose transporter.
Clinically, the chemical is used for the treatment of pancreatic β cell carcinoma.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How should I store Product S0130, Streptozocin, upon receipt?

    Streptozocin should be stored at -20 degrees C with desiccation.  The desiccant is to prevent moisture uptake which can shorten shelf-life.

  3. How do I store solutions of Product S0130, Streptozocin?

    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.

  4. What is the half-life of Product S0130, Streptozocin?

    Streptozocin has a reported half life of 15 to 30 minutes.

  5. How can I make a solution of Product S0130, Streptozocin?

    This product dissolves in water at 50 mg/mL to give a light yellow solution, from clear to slightly hazy. We recommend using a 20 mM citrate buffer at pH 4.5 for best solution stability.

  6. Can Product S0130, Streptozocin, be used to induce diabetes?  What concentration should be used?

    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).

  7. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.
