【Detection principle】 This product uses fluorescence immunochromatography to quantitatively detect the content of cCRP in whole blood, serum / plasma. Basic principle: T and C lines are marked on the nitrocellulose membrane, and the T line is coated with an antibody a that specifically recognizes the cCRP antigen. The binding pad is sprayed with another fluorescent nanomaterial-labeled antibody b that can specifically recognize cCRP. The cCRP in the sample is first combined with the nanomaterial-labeled antibody b to form a complex, which is then chromatographed upward. The complex is combined with T-line antibody a Combined to form a sandwich structure, when the excitation light is irradiated, the nanomaterial emits a fluorescent signal, and the strength of the signal is positively related to the cCRP concentration in the sample.
