Anti-RLK antibodies enable researchers to detect and measure the RLK antigen in biological samples. This target is a reported synonym of the TXK gene, which encodes TXK tyrosine kinase. This protein is known to function in adaptive immune responses and the regulation of transcription, among other biological roles. The human version of RLK has a canonical amino acid length of 527 residues and a protein mass of 61.3 kilodaltons. It is reported to be localized in the cell membrane, nucleus, and cytoplasm of cells. Other names for this target antigen include BTKL, PSCTK5, and PTK4. Indicated applications for RLK antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry.
