Anti-SYCP1 antibodies are used in the immunodetection of the protein synaptonemal complex protein 1. In humans, the canonical protein has a reported length of 976 amino acid residues and a mass of 114.2 kDa. Its subcellular localization is in the nucleus. It is notably expressed in the testis. SYCP1 is reported to be a major component of the transverse filaments of synaptonemal complexes, formed between homologous chromosomes during meiotic prophase. Synonyms for this target antigen include HOM-TES-14, SCP-1, SCP1, cancer/testis antigen 8, testicular tissue protein Li 191, and CT8. SYCP1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 80 citations in the literature describe the use of SYCP1 antibodies in research. Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
