Anti-citrullinated protein antibodies (ACPAs) are autoantibodies (antibodies to an individual’s own proteins) that are directed against peptides and proteins that are citrullinated. They are present in the majority of patients with rheumatoid arthritis. Clinically, cyclic citrullinated peptides (CCP) are frequently used to detect these antibodies in patient serum or plasma (then referred to as anti–citrullinated peptide antibodies).During inflammation, arginine amino acid residues can be enzymatically converted into citrulline residues in proteins such as vimentin, by a process called citrullination. If their shapes are significantly altered, the proteins may be seen as antigens by the immune system, thereby generating an immune response.ACPAs have proved to be powerful biomarkers that allow the diagnosis of rheumatoid arthritis (RA) to be made at a very early stage.

Rat Anti-cyclic Citrullinated Peptide Antibody (CCP-Ab) ELISA Kit employs the competitive enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with an antibody specific to CCP-Ab. Standards or samples are then added to the appropriate microtiter plate wells with a Horseradish Peroxidase (HRP)-conjugated CCP-Ab and incubated. The competitive inhibition reaction is launched between with HRP labeled CCP-Ab and unlabeled CCP-Ab with the antibody. A substrate solution is added to the wells and the color develops in opposite to the amount of CCP-Ab in the sample. The color development is stopped and the intensity of the color is measured.
