Anti-Syk Antibody

Spleen tyrosine kinase (Syk) is a 72 kDa non-receptor tyrosine kinase central to immunoreceptor signaling cascades, including B-cell receptor, Fc receptor, and integrin pathways. This rabbit polyclonal reagent from Antibodies.com is raised against Syk and validated for Western blot and immunohistochemistry workflows on human, mouse, and rat samples. The unconjugated antibody is supplied at 1 mg/ml in PBS containing 0.1% sodium azide and 50% glycerol as a cryoprotectant, packaged as a 100 µl vial that supports multiple immunoblots or tissue sections. Storage at -20 °C preserves activity across freeze-thaw cycles, and the polyclonal format provides recognition of multiple epitopes on the kinase. Syk is widely used as a marker for B-lineage lymphoid cells and is studied in mast cell signaling, platelet activation, and immune cell development, making this reagent useful across immunology and hematology research programs.
