These BRK ELISA kits are immunodetection tools for measuring the levels of BRK in biological samples. BRK is an alias of the human PTK6 gene, which encodes the protein, protein tyrosine kinase 6. Notably, BRK is known to play a role in cell differentiation and cell migration, among other functions. The PTK6 protein is 451 amino acid residues in length and 51.8 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue specificity, it is reported to have epithelia-specific expression. This protein is known to be phosphorylated. Other names for this target antigen include PTK6 protein tyrosine kinase 6. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
