The GST•Tag™ Assay Kit is designed to perform quantitative colorimetric enzymatic assays of glutathione-S-transferase (GST) fusion proteins (Habig 1974). The kit is useful for the quantification of GST activity in crude samples or purified fractions. The suitability of this assay for crude samples allows expression conditions to be evaluated and rapidly optimized by comparing GST activity levels. The GST activity assay is simple to perform using the supplied 1-chloro-2,4-dinitrobenzene (CDNB) substrate. A sample is combined with CDNB substrate in the supplied reaction buffer and the absorbance of the reaction is monitored at 340 nm. The rate of change in A340 is proportionate to the amount of GST activity present in the sample. The assay has sufficient sensitivity to detect as little as eight pmol of functional GST, which corresponds to approximately 250 ng of unfused GST.
