C-Reactive Protein (CRP) Antigen >99%

Refined to a purity exceeding 99% and supplied as a 1 mg liquid preparation, this C-Reactive Protein (CRP) antigen from Antibodies.com supports immunodiagnostic assay development, inflammation research, and antibody production workflows. Investigators use the reagent as a calibrator or positive control in immunoassays designed to quantify CRP, and as an immunogen for raising polyclonal and monoclonal antibodies in host species such as rabbit, goat, and mouse. Application areas include ELISA plate coating, western blot standards, immunoturbidimetric assay calibration, and dot blot analysis. Researchers studying the acute-phase response, pentraxin family structure-function relationships, cardiovascular risk biomarkers, and inflammatory disease models rely on highly purified CRP antigen for reproducible binding studies and inhibitor screens. The liquid format allows direct dilution into coating buffer or PBS without resolubilization, and aliquoting into smaller working volumes is recommended to limit freeze-thaw cycles of any unused material. For long-term integrity, the stock should be stored frozen and protected from light, with working aliquots kept refrigerated between uses. Each preparation is delivered in a single vial containing 1 mg of protein, providing ample material for multiple assay optimization runs and antibody production campaigns.
