Anti-KCP antibodies are used in the immunodetection of the protein kielin cysteine rich BMP regulator. In humans, the canonical protein has a reported length of 1568 amino acid residues and a mass of 166.9 kDa. It has been described to be a secreted protein. Up to 3 different isoforms have been reported for this protein. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include cysteine rich BMP regulator 2 (chordin-like), cysteine-rich motor neuron 2 protein, kielin/chordin-like protein 1, and kielin/chordin-like protein. KCP gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. ELISA and Western Blot are common applications for Kcp antibodies.
