WebThe Malachite Green Phosphate Detection Kit is designed for the in vitro measurement of phosphatase activity. Protein phosphatase enzymatic activity results in the release into solution of free inorganic phosphate from protein-phosphatase substrates. This free inorganic phosphate then forms a green molybdophosphoric acid complex.
