Anti-QSER1 antibodies are used in the immunodetection of the protein glutamine and serine rich 1. In humans, the canonical protein has a reported length of 1735 amino acid residues and a mass of 190 kDa. Its subcellular localization is in the chromosomes. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. QSER1 is known to play an important role in the protection and maintenance of transcriptional and developmental programs. Synonyms for this target antigen include glutamine and serine-rich protein 1. QSER1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is a widely used application for the QSER1 antibodies listed below. In addition, Immunohistochemistry is also a common application.
