Anti-Synaptophysin Antibody

This polyclonal antibody from Antibodies.com specifically recognizes synaptophysin, a ~38 kDa integral membrane glycoprotein localized to the presynaptic vesicle membrane of neurons and neuroendocrine cells. The reagent is widely used as a marker for neuronal differentiation and for the characterization of neuroendocrine tumors such as pheochromocytoma and small cell lung carcinoma. The unconjugated IgG is supplied as 100 µg in liquid format and validated for Western blot detection of endogenous synaptophysin in human, mouse, and rat samples. For best results, store frozen at -20°C in working aliquots to limit freeze-thaw cycles and preserve binding activity across downstream immunoblotting workflows.
