A kind of colloidal gold platform cleaning solution

Abstract

The invention provides a colloidal gold platform cleaning solution. The cleaning solution comprises (1) 0.25-2g / L of alkali metal hydroxide; (2) 0.25-30g / L nonionic surfactant; (3) 2-11g / L of buffering agent; and (4) 0.1-4g / L of bacteriostatic agent. The cleaning solution is low in price, favorable in stability and less possible to remain, and does not affect the determination of a colloidal gold platform.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a colloidal gold platform cleaning solution. Background technique [0002] Colloidal gold test paper is a kind of dry immunoassay product that has been clinically used for many years and is characterized by convenient operation, qualitative detection, fast reporting speed and wide adaptability. With the increasing demand for quantitative, accurate, and high-throughput in the domestic clinical diagnostic industry in recent years, colloidal gold diagnostic test strips are evolving towards accurate quantitative, fully automated detection, and miniaturized POCT. In clinical laboratories, colloidal gold-based POCT samples are generally serum, plasma, and whole blood. Therefore, the fully automatic fluid system is easily polluted by blood cells, proteins, crystals, etc., which breeds bacteria and causes abnormalities in the detection. result. It can be seen that the effective...
