Anti-PGA5 Antibody

Pepsinogen A Research Reagent

The PGA5 gene encodes pepsinogen A, a zymogen secreted by gastric chief cells that is converted into active pepsin in the acidic environment of the stomach. This unconjugated rabbit polyclonal IgG antibody from Antibodies.com is raised against human PGA5 and validated for Western blot detection in human-derived samples. Provided as a 100 µl liquid aliquot, it allows laboratories to pair the reagent with their preferred secondary label, HRP conjugate, or fluorescent detection chemistry for downstream blotting workflows.

Researchers commonly apply this reagent for western blot analysis of gastric tissue lysates, studies of pepsinogen expression patterns, and characterization of digestive enzyme zymogens in cell biology research. The polyclonal format offers recognition of multiple epitopes, which can support stronger signal intensity and broader target capture than monoclonal alternatives. Refrigerate the vial upon arrival and aliquot into single-use portions to limit freeze-thaw cycles and preserve antibody activity.
