XTT Cell Viability Assay
TribioScience’s XTT Cell Viability Assay Kit is a colorimetric assay to quantify the viable cells with soluble formazan dye. The formation of orange formazan is based on the reduction of yellow tetrazolium salt (XTT) under the facilitation of electron acceptors or electron coupling reagents with mitochondrial oxidoreductases that only existed in the living cells. The orange formazan dye is soluble in the liquid solution, can be directly quantified by measuring the absorbance at 450 nm wavelength. The assay can be...
