A rapid one-step kinetics-based immunoassay procedure for the highly-sensitive detection of C-reactive protein
A rapid one-step kinetics-based sandwich enzyme-linked immunosorbent (ELISA) procedure has been developed for highly-sensitive detection of C-reactive protein (CRP) in less than 30 min. With minimal process steps, the procedure is highly simplified and cost-effective. The analysis only involves sequentially the formation of a sandwich immune complex on capture anti-CRP antibody (Ab)-bound Dynabeads, followed by two magnet-assisted washings and an enzymatic reaction. The developed immunoassay (IA) detected CRP in the dynamic range of 0.3-81 ng mL-1 with a limit of detection and analytical sensitivity of 0.4 ng mL-1 and 0.7 ng mL-1. Its analytical precision for analysis of CRP spiked in diluted human serum, whole blood, and ethylenediaminetetraacetic acid (EDTA) plasma samples of patients was validated by conventional ELISA, unravelling its immense potential for in vitro diagnostics (IVD).
