Anti-STK3 / STK4 Antibody

This rabbit polyclonal antibody from Antibodies.com targets the serine/threonine kinases STK3 (also known as MST2) and STK4 (MST1), the core kinases of the Hippo signaling pathway that govern organ size control, cell proliferation, and apoptotic responses. The reagent is supplied as a 100 µl liquid aliquot in an unconjugated format suitable for direct labeling or downstream secondary detection. Validation has been performed for Western blot (WB) and immunohistochemistry (IHC) on human and mouse tissue, supporting research into Hippo-pathway-dependent tumor suppression and stress-induced apoptosis. Polyclonal reactivity across multiple epitopes of the target kinases is intended for detection of full-length and processed kinase species in cell lysates and fixed tissue sections. For storage, keep the vial at -20 °C in working aliquots to limit freeze-thaw cycles and preserve binding activity across repeated blotting and imaging runs.
