3 PRINCIPLE OF THE METHOD
After ultrasonic plastic filtrate obtained after extraction for subsequent testing. Microtiter plates in a fixed amount of bisphenol A conjugate antigens, plus
After the sample solution or a standard solution of bisphenol A, followed by the addition of bisphenol A certain amount of specific antibody, and the immobilized antigen so that the antigen competition
With contention free in solution of bisphenol A specific antibody binding, thoroughly washed unreacted antibody and antigen, and then adding a certain amount of enzyme
Secondary antibody (anti-antibody) amplifying effect, followed by sufficient washing, chromogenic substrate VIS color. As a result, the more the antigen content of the solid phase antibody
The less bound antibody, the amount of enzyme-labeled secondary antibody, the less, the color the more shallow, negative correlation between the two. The conditions for this experiment are. fixed limit antigen, anti
Quantitative body, anti-HRP II limits. The same site with the immobilized antigen and antibody binding to the antigen, the antibody binding competitively.
