Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Useful in AIDS and cancer testing.
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.

Principle

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

2, 3-bis (2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino) carbonyl]-2H-tetrazolium hydroxide (XTT) reduction assay has been used to study Candida biofilm formation. However, considering that the XTT reduction assay is dependent on cell activity, its use for evaluating mature biofilms may lead to inaccuracies since biofilm
