Anti-BRK antibodies enable researchers to detect and measure the BRK antigen in biological samples. This target is a reported synonym of the PTK6 gene, which encodes protein tyrosine kinase 6. This protein is known to function in cell differentiation and cell migration, among other biological roles. The human version of BRK has a canonical amino acid length of 451 residues and a protein mass of 51.8 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. This target antigen may also be known as PTK6 protein tyrosine kinase 6. Western Blot is the most common application for the BRK antibodies listed below. ELISA and Immunohistochemistry are also common applications.
