Anti-CBX2 antibodies are used in the immunodetection of the protein chromobox 2. In humans, the canonical protein has a reported length of 532 amino acid residues and a mass of 56.1 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the testis. CBX2 is a known component of the Polycomb group (PcG) multiprotein PRC1-like complex, a complex class required to maintain the transcriptionally repressive state of many genes, including Hox genes, throughout development. Synonyms for this target antigen include Pc class homolog, cell division cycle associated 6, chromobox homolog 2 (Pc class homolog, Drosophila), modifier 3, and chromobox protein homolog 2. CBX2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of CBX2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
