Anti-VAPA Antibody

VAPA (VAMP-Associated Protein A) is an integral endoplasmic reticulum membrane protein that participates in vesicle trafficking, SNARE-mediated membrane fusion events, and inter-organelle lipid transport between the ER and other membrane compartments. This rabbit polyclonal antibody from Antibodies.com is raised against VAPA and validated for Western blot (WB) and immunohistochemistry (IHC) workflows on human and mouse samples. The unconjugated reagent is supplied as 100 µl of polyclonal antiserum intended for research use only, allowing flexibility in downstream detection chemistry and secondary antibody selection. The antibody recognizes endogenous VAPA, which has been studied in the context of ER-mitochondria tethering, the unfolded protein response, and membrane contact site biology. Researchers investigating vesicle-associated membrane protein interactions, ER architecture, or related trafficking pathways can apply this reagent to detect VAPA in cell and tissue lysates by WB or to localize the protein in fixed sections by IHC. The polyclonal format offers broader epitope coverage for VAPA detection across experimental conditions, and the rabbit host is compatible with common anti-rabbit secondary detection systems used in standard immunoblotting and immunostaining protocols.
