Proteintech Group


100% Original Products, 0% OEM

Unlike Abcam & Santa Cruz has so many products from OEM (貼牌生產), Proteintech make 100% antibodies from start to finish, so we know every last detail about each one. Plus, we test every antibody in a variety of applications as standard, refusing to sell any that fail Western blotting using whole tissue or cell lysates.

The Whole-Protein Advantage

Antibody raised from whole protein, not peptides. The benefits of whole-protein antibodies, among others, are their robustness and versatility. Over 95% of our antibodies are raised against whole protein immunogens, resulting in higher binding sensitivities. This means greater successes in a wider range of applications and species.

100% Validation

Study the schematic, which shows our validation hierarchy. You’ll notice that we don’t sell any antibodies that do not have a valid Western blot (WB) or immunohistochemistry (IHC). All of Proteintech’s validation results are accessible on its website or through our distributor – ATCG Limited. Over 20,000 publications now feature Proteintech products worldwide.

100% commitment

We cover all our products with our hassle-free, full money-back refund – we don’t think you’ll need to use it, but it’s there just in case. Our guarantee gives you the confidence to put our antibodies to the test in a risk-free environment. Species or application not listed on our datasheet? That doesn’t matter; it will still be covered by our guarantee.
