Biological description
Tetrazolium sodium salt for use in colorimetric assays for cell viability and proliferation. Cleavage of XTT by dehydrogenase enzymes of metabolically active cells yields a highly colored, water soluble formazan product, an advantage over the use of MTT due to MTT requiring a formazan crystal solubilization step. Has been used to asses valvular injury for testing cryopreserved cardiac valves.

Handling
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
