Anti-MMP8 antibodies are used in the immunodetection of the protein matrix metallopeptidase 8. In humans, the canonical protein has a reported length of 467 amino acid residues and a mass of 53.4 kDa. Its subcellular localization is in the extracellular matrix and cytoplasm. A member of the Peptidase M10A protein family, it is known to be involved with endodermal cell differentiation and extracellular matrix organization. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include HNC, PMNL-CL, neutrophil collagenase, PMN leukocyte collagenase, PMNL collagenase, and CLG1.
