生物活性

製品説明 WST-8 is a water-soluble tetrazolium salt used for assessing cell metabolic activity that produces corresponding formazan dye that absorbs at 460 nm. WST-8 is typically used as a cell viability indicator in cell proliferation assays.
in vitro

WST-8 is reduced by NADH in good yields at neutral pHs in the presence of 1-methoxy PMS to produce the corresponding formazan dye that absorbs at 460 nm. The formazan is soluble to water at concentrations higher than 0.1 M. WST-8 is useful as a sensitive chromogenic indicator for NADH. It is also applicable to cell proliferation assays as a cell viability indicator.[1]

細胞アッセイ 細胞株 Hela cells
濃度 0.5 mM
反応時間 2 h
実験の流れ

A hundred μl of HeLa cell culture in the logarithmic phase is inoculated onto a 96-well microtiter plate, and the plate pre-incubated for 24 h in a CO2 incubator at 37℃. A 10 μl of the working solution containing WST-8 and lmethoxy PMS (0.5 mM and 20 μM, respectively, as the final concentration) is added to each well; it is incubated for an additional 2 h. The absorbance of each well is measured at 450 nm with a reference wavelength at 650 nm with an M-UVmax microplate reader.
