Anti-Chk2 antibodies enable researchers to detect and measure the Chk2 antigen in biological samples. This target is a reported synonym of the CHEK2 gene, which encodes checkpoint kinase 2. This protein is known to function in cell division and DNA damage pathways, among other biological roles. The human version of Chk2 has a canonical amino acid length of 543 residues and a protein mass of 60.9 kilodaltons, although 13 isoforms have been identified. 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 CDS1 and HuCds1. Western Blot is the most common application for the Chk2 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
