摘要:
A multiple enzyme method for spectrophotometrical measurement of K, Na ATPase activity is described. The method includes three enzymatic steps: Hydrolyses of ATP by ATPase, conversion of inosine to hypoxanthine and ribose -1- phosphate by purine nucleoside phosphorylase and finally xanthine oxidase mediated oxidation of hypoxanthine to xanthine with consequent formation of formazan from a tetrazolium salt. The phospholytic cleavage of inosine in the medium is dependent of an ATPase- phosphate complex.
