Anti-NCF1 antibodies are used in the immunodetection of the protein neutrophil cytosolic factor 1. In humans, the canonical protein has a reported length of 390 amino acid residues and a mass of 44.7 kDa. Its subcellular localization is in the membrane and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably expressed in peripheral blood monocytes and neutrophils. NCF1 is known to be involved with the apoptotic pathway and carbohydrate metabolism and homeostasis. The NCF1 gene has been associated with the disease, Granulomatous disease. Synonyms for this target antigen include 47 kDa autosomal chronic granulomatous disease protein, 47 kDa neutrophil oxidase factor, NADPH oxidase organizer 2, NCF-47K, SH3 and PX domain-containing protein 1A, and neutrophil cytosol factor 1. NCF1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 120 citations in the literature describe the use of NCF1 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
