Anti-TNP2 antibodies are used in the immunodetection of the protein transition protein 2. In humans, the canonical protein has a reported length of 138 amino acid residues and a mass of 15.6 kDa. Its subcellular localization is in the nucleus. It is noted to be expressed by spermatids. A member of the Nuclear transition protein 2 protein family, TNP2 is known to play an important role in the replacement of histones to protamine in the elongating spermatids of mammals. Synonyms for this target antigen include nuclear transition protein 2, TP-2, transition protein 2 (during histone to protamine replacement), and TP2. TNP2 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Western Blot is the most common application for the TNP2 antibodies listed below. ELISA and Immunofluorescence are also common applications.
