After the manner assays of the esterase total activity with naphthol-α-acetate as substrate, addion naphthol-β-acetate, α-NA: β-NA=2:1 (moles),mix and by which means polyrinyl pyrrolindone as stabilizer of the substrates emulsion. The stabilizer in use quantity and the condition of dilution stability of the mixed substrates and produets emulsion were investigated. A new method which assays of the total activity with multiple forms esterase was constituted. Using this mothod, we measured total activity of es...
