Abstract

The method includes steps: chemical reaction produces stable single oxygen source; reaction between single state oxygen and high selectivity, high sensitive chemiluminescence probe produces intermediate product in high energy, and sending out photons caused by deexcitation quickly; albumin in minute quantities combined with FCLA enhances sensitivity of chemiluminescence intensity; it is linear relation between magnitude of chemiluminescence enhanced sensitivity and concentration of albumin; using change of luminous intensity corresponding to change of concentration of albumin can detect albumin in trace amount. Equipment for implementing the method includes darkroom, sample cell, sample injector in minute quantities, integrating sphere, module for receiving chemiluminescence, module for treating electrical pulse, and computer etc. Features are: small sample needed, short time consumption, low cost, high sensitivity, and certain degree of interference immunity.

Description

technical field [0001] The invention relates to a technology for detecting microalbumin, in particular to a chemiluminescence method and a device for detecting microalbumin with high sensitivity. Background technique [0002] Serum albumin (HSA) is the most abundant protein in serum, accounting for about 40% to 60% of the total serum protein. It plays an important role in the transportation of drugs and maintaining normal blood osmotic pressure. [0003] At present, the commonly used methods for analyzing albumin are: (1) dry test strip detection method; using the protein error principle of the indicator (that is, the indicator ion is combined with the opposite charge of the albumin, so that it reacts with the displayed pH color Change to a higher pH color change, the magnitude of this pH color change is proportional to the albumin content) established. (2) Heating acetic acid method: heating and boiling to denature and coagulate the protein, and then adding acid to make t...
