CCP peptide 

CCP peptide is a synthetic cyclic citrullinated peptide (CCP) and used as the substrate for detecting anti-CCP antibodies serologically. CCP peptide functions as a target for autoantibodies with a very high specificity for rheumatoid arthritis (RA)^[1][2].

CCP peptide is used as a new antigenic substrate in anti-CCP ELISA to detect anti-citrullinated protein antibodies (ACPAs). The anti-CCP ELISA is extremely specific (98%), with a reasonable sensitivity (68%). The anti-CCP ELISA is very useful for diagnostic and therapeutic strategies in rheumatoid arthritis (RA)^[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
