|Description||Streptozotocin is a glucosamine-nitrosourea derivative, which is a methylating, carcinogenic, antibiotic and diabetes inducing agent.|
Streptozotocin directly methylates DNA and is highly genotoxic, producing DNA strand breaks, alkali-labile sites, unscheduled DNA synthesis, DNA adducts, chromosomal aberrations, micronuclei, sister chromatid exchanges, and cell death. Free radicals are involved in the production of DNA and chromosome damage by Streptozotocin.  Streptozotocin is toxic to pancreatic beta cell. Exposed to 15 mM Streptozotocin for 1 hr followed by a 24 hrs recovery period induces apoptosis in murine pancreatic beta cell line, INS-1. Streptozotocin (30 mM) causes the cells to undergo necrosis (22%) as well as apoptosis (17%). 
|In vivo||Streptozotocin is often used to induce diabetes mellitus in experimental animals. Streptozotocin is selectively accumulated in pancreatic beta cells via the low-affinity GLUT 2 glucose transporter. Streptozotocin (60 mg/kg) injection for 4 month induces rapid degranulation of beta cells without necrosis, development of cataracts and accumulation of glycogen in the proximal convoluted tubules of the kidney. Streptozotocin (100 mg/kg) produces lesions in the exocrine cells of the pancreas, and persistence of small, possibly secretory, granules in the Golgi zone of beta cells in rats of ‘Streptozotocin diabetes’.  Streptozotocin is found to be carcinogenic in rats, mice and hamster. A single administration of Streptozotocin is able to induce tumors in kidney, liver, lung, pancreas, uterine and liver tumors in hamster. Intraperitoneally injected with Streptozotocin (100-150 mg/kg) for normotensive Wistar Kyoto rats (WKY) for 12 months induces carcinogenesis with tumors incidence of 70% in liver, 20% in kidney and 10% in liver and kidney. |

|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
