Anti-CPK antibodies enable researchers to detect and measure the CPK antigen in biological samples. This target is a reported synonym of the PIK3C2A gene, which encodes phosphatidylinositol-4-phosphate 3-kinase catalytic subunit type 2 alpha. This protein is known to function in cell migration and endocytosis, among other biological roles. The human version of CPK has a canonical amino acid length of 1686 residues and a protein mass of 190.7 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane, nucleus, cytoplasmic vesicles, Golgi, and cytoplasm of cells. Other names for this target antigen include OCSKD and PI3-K-C2(ALPHA). Indicated applications for CPK antibodies listed below include ELISA, Western Blot, Immunocytochemistry, and Immunohistochemistry.
