Background Information

VAPA (Vesicle-associated membrane protein-associated protein A), also known as VAP33, is a ubiquitously expressed integral membrane protein of the VAMP-associated protein (VAP) family. It is present in the plasma membrane and in intracellular vesicles, playing a role in vesicle trafficking.

The reviews below have been submitted by verified Proteintech customers who received an incentive forproviding their feedback.

FH Janathan (Verified Customer) (12-21-2023)	Really good and strong signal in WB and IF. IP works on WB, but not sensitive enough for visualizing with coomassie Applications: Western Blot, Immunofluorescence, Immunoprecipitation Primary Antibody Dilution: WB: 1:1000 IF: 1:100 IP: 1ug per 1000 ug protein Cell Tissue Type: Human skin fibroblasts
FH Wei (Verified Customer) (09-22-2020)	The antibody have high specific band in western blot, but not so good for heart sections. Applications: Western Blot, Immunofluorescence Cell Tissue Type: Mouse Heart
