What is XTT sodium salt?

The Uses of XTT sodium salt

Tetrazolium derivative useful in cancer research.XTT sodium salt is used in conjunction with phenazine methosulfate to screen human cancer cell lines. It is also used to study fungal cell damage. It is involved in testing antimicrobial susceptibility of staphylococci and in candida biofilm research. Further, it is used in an assay for cell viability and cell proliferation.

The Uses of XTT sodium salt

General Description

XTT (sodium 3′-[1-[(phenylamino)-carbony]-3,4-tetrazolium]-bis(4-methoxy-6-nitro)benzene-sulfonic acid hydrate) is a tetrazolium salt, which forms water-soluble formazan on bioreduction.

Biochem/physiol Actions

XTT (sodium 3′-[1-[(phenylamino)-carbony]-3,4-tetrazolium]-bis(4-methoxy-6-nitro)benzene-sulfonic acid hydrate) is acted upon by dehydrogenases present in metabolically active cells. This produces water soluble formazan, which is a highly colored product. Thus, it offers an advantage in colorimetric proliferation assays, as opposed to MTT, as the product is already soluble and no formazan crystals are formed.
