Anti-FPR3 antibodies are used in the immunodetection of the protein formyl peptide receptor 3. In humans, the canonical protein has a reported length of 353 amino acid residues and a mass of 40 kDa. Its subcellular localization is in the cell membrane. It is notably expressed in various tissues with highest expression in the lung. A member of the G-protein coupled receptor 1 protein family, FPR3 is known to be involved with chemotaxis and inflammatory response pathways. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include FMLP-R-II, FMLPY, FPRH1, FPRH2, FPRL2, RMLP-R-I, N-formyl peptide receptor 3, and FML2_HUMAN. FPR3 gene orthologs have been reported in the mouse, rat and chimpanzee species. A number of FPR3 antibodies have been mentioned in research publications and have associated citations. ELISA, Flow Cytometry, Western Blot, and Immunohistochemistry are common applications for these antibodies.
