Abstract

The invention relates to a kit for diagnosing adenosine deaminase by utilizing the technologies of the enzymic colorimetric method and the enzyme linked immunosorbent assay (ELISA). The invention further relates to a method, a principle and the composition and the components of a reagent for mensurating the active concentration of the adenosine deaminase, and belongs to the technology field of medical inspection and measurement. The main components of the kit include a buffer solution, reduced coenzyme, glutamine synthetase, pyruvate carboxylase, octopine dehydrogenase, adenosine, glutamic acid, adenyl pyrophosphate, phosphate, oxaloacetic acid, arginine and a stabilizer. Through mixing a sample and the reagent by a certain volume ratio, a series of enzymatic reactions occur, then the reactant is placed under an ultraviolet / visible light analyzer, and the velocity of the decrease in absorbance at 340nm of the dominant wavelength is detected, thereby mensurating the active concentration of the adenosine deaminase. By adopting the kit, the required mensuration results can be completely obtained through an ultraviolet / visible light analytical instrument.

Description

technical field [0001] The invention relates to a diagnostic kit for adenosine deaminase, and at the same time, the invention also relates to a method for measuring the activity concentration of adenosine deaminase, which belongs to the technical field of medical examination and measurement. Background technique [0002] Medical research shows that adenosine deaminase is a nucleic acid metabolizing enzyme that has an important relationship with the body's cellular immune activity. Therefore, the determination of adenosine deaminase activity is used as an important diagnostic marker for the differential diagnosis of benign and malignant hydrothorax, cerebrospinal fluid, severe combined immunodeficiency disease (SCID), acute and chronic hepatitis, liver cirrhosis, liver cancer and other diseases. [0003] The methods for determining the activity of adenosine deaminase mainly include radionuclide method, physical method and biochemical method. As far as the applicant knows, th...
