Description

WST-8 is a water-soluble tetrazolium salt (2-(2-Methoxy-4-nitrophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium Sodium Salt), also known as 2-(2-methoxy-4-nitrophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium monosodium salt in Chinese. Its molecular formula is C20H13N6NaO11S2, with a molecular weight of 600.47. It has a CAS Number of 193149-74-5 and a purity of >98%. WST-8 appears as a light yellow solid.

WST-8 is a compound similar to MTT. In the presence of electron coupling reagents, it can be reduced by some dehydrogenases in mitochondria to produce an orange-colored formazan.

WST-8 is an upgraded alternative to MTT and offers distinct advantages over MTT or other MTT-related products such as XTT and MTS. Firstly, the formazan produced by MTT reduction is not water-soluble and requires specific solvents for dissolution, whereas the formazan generated by WST-8, XTT, and MTS is water-soluble, eliminating the need for additional dissolution steps. Secondly, the formazan produced by WST-8 is more soluble than that produced by XTT and MTS. Thirdly, WST-8 is more stable than XTT and MTS, leading to more stable experimental results. Additionally, WST-8 has a wider linear range and higher sensitivity compared to XTT and MTS.

Compared to WST-1, WST-8 offers higher detection sensitivity, better solubility, and increased stability.

This product is soluble in water, methanol, DMSO, and other solvents.

WST-8 can be used as a chromogenic indicator for NADH and is commonly used for cell proliferation and cytotoxicity assays.
