Anti-NPFF antibodies are used in the immunodetection of the protein neuropeptide FF-amide peptide precursor. In humans, the canonical protein has a reported length of 113 amino acid residues and a mass of 12.4 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. A member of the FARP (FMRFamide related peptide) protein family, NPFF is known to be involved with chemical synaptic transmission. Synonyms for this target antigen include FMRFAL and pro-FMRFamide-related neuropeptide FF. NPFF gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of Npff antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
