Anti-VASP (phospho S157) Antibody

VASP (Vasodilator-Stimulated Phosphoprotein) is a key regulator of actin cytoskeleton dynamics, and phosphorylation at serine 157 is widely used as a downstream readout of cAMP/PKA signaling in platelets, endothelial cells, and smooth muscle. This polyclonal rabbit antibody from Antibodies.com targets the phospho-S157 epitope specifically, enabling researchers to distinguish the activated, PKA-phosphorylated pool of VASP from total protein in Western blot and immunohistochemistry workflows.

The unconjugated IgG reagent is supplied as 50 µl of stock and is reactive against human, mouse, and rat samples, supporting cross-species studies in vascular biology, platelet activation assays, and cell migration research. The antibody is provided in a vial suitable for aliquoting on arrival to minimize freeze-thaw cycles, and refrigerated storage helps preserve phospho-specific binding activity over the product shelf life. Researchers commonly pair this reagent with a total VASP loading control when assessing PKA pathway activation across cell types.
