Anti-H13 antibodies enable researchers to detect and measure the H13 antigen in biological samples. This target is a reported synonym of the HM13 gene, which encodes histocompatibility minor 13. This protein is known to function in in utero embryonic development, among other biological roles. The human version of H13 has a canonical amino acid length of 377 residues and a protein mass of 41.5 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the ER and cell membrane of cells and notably expressed in many tissues, such as the endometrium and epididymis. H13 is a member of the Peptidase A22B protein family. Immunofluorescence is a widely used application for the H13 antibodies listed below. In addition, Western Blot is also a common application.
