Cleaver Scientific
Available in single and dual wavelength formats, in 21x21cm and 21x26cm sizes, our transilluminators are supplied either as standalone units or with the MicroDOC, as part of a fully integrated gel documentation system. With a large surface area, each transilluminator serves as the perfect workstation for viewing and working with fluorescently-stained protein and nucleic acid gels.
Standard features include a high/low intensity safety switch and an efficient starter that allows each of the six 8-Watt UV tubes to energise quickly without flickering, while special filter glass minimises unwanted background light. All of these features maximise contrast and sensitivity, allowing even the faintest fluorescent gels to be viewed. Two dual wavelength models offer added flexibility and convenience.

Streptozocin or streptozotocin, is obtained from Streptomyces achromogenes.[1] 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.

Storage conditions and Shelf life
Store the dehydrated medium at 10-30°C and use before the expiry date on the label.
Store the prepared medium at 15-25°C.
Precautions
A small amount of blue colour at the top of the bottle indicates oxidation. If this colour extends down into the medium it should be discarded.
Avoid prolonged heating in open flasks, during the preparation of the medium, because thioglycollate is volatile.
Sodium glycerophosphate may be metabolised by some organisms and thus promote their growth.
