Pepsin A-4 Antibodies

AND PGA4 ELISA kits, Pepsin A-4 Proteins

Many biological assays use antibodies to detect Pepsin A-4, such as Western Blot (WB), ELISA, Flow Cytometry, Immunocytochemistry (IHC). These antibodies can be polyclonal or monoclonal, and react with Pepsin A-4 in Human, Mouse, Rat, and many other animal samples. Boster Bio use mainly mouse and rabbit to develop Pepsin A-4 antibodies...

We validate the specificity of these antibodies to Pepsin A-4 by testing them on tissues known to express PGA4 positively and negatively. Browse below to find the PGA4 antibody that suites your experiment. We have 3 of these antibodies and many publications and validation images.

If you cannot find antibodies that fit your needs, contact us for making custom antibodies. We have a full suite of custom antibody services covering from research to diagnostic and therapeutic applications.
