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.

Application

XTT sodium salt has been used to assess cell viability.
XTT has been used in conjunction with phenazine methosulfate (PMS) to screen human cancer cell lines. The tetrazolium dye has also been used to study fungal cell damage, in testing antimicrobial susceptibility of staphylococci, and in Candida biofilm research. Limitations to the XTT assay have been reported.

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.

Principle

In living cells, XTT is metabolically reduced to produce a colorimetric, water-soluble formazan product.
