Buffer solution for electrochemiluminescence immunity analyzer and preparation method of buffer solution

Abstract

The invention belongs to agents for medical diagnostic apparatuses, and in particular relates to a buffer solution for an electrochemiluminescence immunity analyzer and a preparation method of the buffer solution. The buffer solution for the electrochemiluminescence immunity analyzer comprises the following components: potassium dihydrogen phosphate 4, tween-20, dodecyl polyglycol ether, polidocanol, tripropyl amine and citric acid; and the pH value of the buffer solution is 6.5-7.0. The buffer solution for the electrochemiluminescence immunity analyzer is simple to prepare and less in usage amount of tripropyl amine to reduce harms of tripropyl amine to bodies of operators and reduce the burden of the environment; the R value of a correlation coefficient after linear regression reaches more than 0.99 compared with an imported buffer solution for an electrochemical immunity analyzer and expresses relatively good relativity; and moreover, the buffer solution is low in production cost, and the selling price can be reduced by 30% compared with a reagent for an equivalent blood cell analyzer on the market, so that the buffer solution for the electrochemiluminescence immunity analyzer is beneficial for large-scale popularization and application.

Description

technical field [0001] The invention belongs to reagents for medical diagnostic instruments, in particular to a buffer solution for electrochemiluminescence immunoassay analyzers and a preparation method thereof. Background technique [0002] At present, the commonly used methods for the quantitative detection of disease-related trace substances in the human body include chemiluminescence immunoassay and electrochemiluminescence immunoassay. The precision is high, and the reagent is stable, and it can be analyzed fully automatically, so it is an ideal marker immunoassay method. [0003] However, the electrochemiluminescence immunoassay is known for its high sensitivity (up to 10 -11 ~10 -17 mol / L) and good repeatability have been widely used. Electrochemiluminescence immunoassays are divided into luminescent systems of organic compounds and luminescent systems of inorganic substances. Organic luminescent substances include hydrazide compounds, acridinium esters and lucig...
