Anti-NANOS2 antibodies are used in the immunodetection of the protein nanos C2HC-type zinc finger 2. In humans, the canonical protein has a reported length of 138 amino acid residues and a mass of 15.1 kDa. Its subcellular localization is in the cytoplasm. It is notably expressed in the testis. A member of the Nanos protein family, NANOS2 is known to play an important role in the sexual differentiation of germ cells by promoting the male fate but suppressing the female fate. Synonyms for this target antigen include nanos homolog 2 and NOS-2. NANOS2 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. A number of NANOS2 antibodies have been mentioned in research publications and have associated citations. ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
