Anti-HP1 alpha antibodies enable researchers to detect and measure the HP1 alpha antigen in biological samples. This target is a reported synonym of the CBX5 gene, which encodes chromobox 5. This protein is known to function in chromatin organization and DNA damage pathways, among other biological roles. The human version of HP1 alpha has a canonical amino acid length of 191 residues and a protein mass of 22.2 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include HEL25, HP1, and HP1A. Western Blot is the most common application for the HP1 alpha antibodies listed below. ELISA and Immunohistochemistry are also common applications.
