Anti-TSPY4 antibodies are used in the immunodetection of the protein testis specific protein Y-linked 4. In humans, the canonical protein has a reported length of 314 amino acid residues and a mass of 35.7 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably expressed in the testis. A member of the Nucleosome assembly protein (NAP) protein family, TSPY4 is suspected to be involved in sperm differentiation and proliferation. Synonyms for this target antigen include testis-specific Y-encoded protein 4. Indicated applications for TSPY4 antibodies listed below include ELISA, Flow Cytometry, Western Blot, and Immunohistochemistry.
