Anti-NLRP4 antibodies are used in the immunodetection of the protein NLR family pyrin domain containing 4. In humans, the canonical protein has a reported length of 994 amino acid residues and a mass of 113.4 kDa. Up to 3 different isoforms have been reported for this protein. A member of the NLRP protein family, NLRP4 is suspected to be involved in inflammation and recognition of cytosolic pathogen-associated molecular patterns (PAMPs) not intercepted by membrane-bound receptors. Synonyms for this target antigen include NACHT, leucine rich repeat and PYD containing 4, PAAD and NACHT-containing protein 2, PYRIN and NACHT-containing protein 2, and NACHT, LRR and PYD domains-containing protein 4. NLRP4 gene orthologs have been reported in the mouse and chimpanzee species. Some NLRP4 antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
