TīmeklisNADH + WST8 NAD+ + Formazan dye The triglycerides test is an enzymatic method. Triglycerides in the sample are hydrolyzed to glycerol and fatty acids by lipoprotein lipase. Glycerol and NAD+ generate dihydroxyacetone and NADH in the prescence of glycerol dehydrogenase. WST8 is reduced to formazan dye by diaphorase and TīmeklisThe tetrazolium salts are cleaved to formazan by cellular enzymes ( Figure 1 ). An expansion in the number of viable cells results in an increase in the overall activity of mitochondrial dehydrogenases in the sample, which in turn increases the amount of formazan dye formed.
