Fluorescence polarization immunoassy and reagents for measurement of c-reactive protein
First Claim
1. A method for determining the presence of concentration of C-reactive protein in a liquid sample of biological fluid, comprising intermixing the a sample of said biological fluid a fluorescent tracer comprising a conjugate of C-reactive protein and a fluorescent moiety, so as to be specifically recognizable by a common antibody or receptor binding site with a solution of an antibody capable of specifically recognizing the C-reactive protein in the sample and the tracer;
- and determining the amount of the tracer which becomes bound to the antibody by fluorescence polarization as a measure of the amount of C-reactive protein in the sample.
