A process for measuring the activity of 5'-nucleotidase includes such steps as proportionally mixing specimen with reagents, enzyme coupling reaction and biochemically analyzing the final resultant to determine the variation in light absorptivity of master wavelength and in turn the activity of 5'-nucleotidase. Its advantages are high sensitivity and precision, and no pollution.

Description

5 '-activity of 5 '-nucleotidase measuring method and 5 '-the phosphonuclease diagnostic kit
Technical field
The present invention relates to a kind ofly to measure 5 '-method of activity of 5 '-nucleotidase, the invention still further relates to simultaneously be used to realize 5 of this method '-the phosphonuclease diagnostic kit, belong to medical test determination techniques field.
Background technology
Medical research shows, 5 '-phosphonuclease (5NT) increases and is mainly seen in the obstructive jaundice, also is found in liver cancer and hepatitis.When the concurrent cholangitis of cholestasis, primary and Secondary cases cholehepatocirrhosis and chronic hepatitis, the 5NT rate of rise is higher than alkaline phosphatase; The susceptibility that 5NT raises when liver tumor and hepatic granuloma is higher than alkaline phosphatase.Because 5 '-activity of 5 '-nucleotidase do not have physiological and raise, and is not only responsive than alkaline phosphatase for diagnosis infant's hepatopathy and gestational liver function cholestasis, and specificity is arranged.Therefore measure 5 '-activity of phosphonuclease is significant for the diagnosis of disease.
5 '-activity determination method of phosphonuclease is a lot, mainly contains isotope substrate method, chemical phosphorus acid test method (nineteen twenty-five).Understand according to the applicant, generally adopt the isotropic substance Substrate test method at present in the world, method is: 5 '-phosphonuclease acts on H 3-dUMP, after the termination reaction,, try to achieve 5 by the ion exchange column analytical results '-activity of 5 '-nucleotidase.Perhaps utilize 5 '-phosphonuclease produces inorganic phosphorus after acting on single adenosine phosphate, analyze content of inorganic phosphorus with Chemical acid method again and calculated 5 '-activity of phosphonuclease.
Method of isotope substrate is complicated to also have isotopic contamination, and needs Isotope analyzer, therefore is difficult to apply conscientiously.Determination of inorganic phosphorus is the method for nineteen twenty-five invention, and accuracy is bad, and strong acid contaminate environment or the like also is not suitable for applying.
Summary of the invention
Propose a kind of can overcome 5 of above prior art shortcoming '-measuring method of activity of 5 '-nucleotidase, provide simultaneously in order to realize 5 of this method '-the phosphonuclease diagnostic kit.Adopt reagent in this test kit not only can on ultraviolet analyser or half, automatic clinical chemistry analyzer, carry out 5 '-activity of 5 '-nucleotidase is measured, and finding speed is fast, accuracy is high, thereby can obtain practical applying.
