Anti-spleen tyrosine kinase antibodies enable researchers to detect and measure the spleen tyrosine kinase antigen in biological samples. This target is a reported synonym of the SYK gene, which encodes spleen associated tyrosine kinase. This protein is known to function in adaptive immune responses and angiogenesis, among other biological roles. The human version of spleen tyrosine kinase has a canonical amino acid length of 635 residues and a protein mass of 72.1 kilodaltons. It is reported to be localized in the cell membrane and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include IMD82, p72-Syk, and tyrosine-protein kinase SYK. A number of spleen tyrosine kinase antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
