Proteintech Group was established by experienced research scientists aiming to provide their fellow research community with superior antibodies and first-class customer service. We are confident that you will be wholly satisfied with our antibodies; the protein origins of Proteintech antibodies make them truly “all-purpose” – they work in a broad spectrum of applications including: WB, IHC, ELISA and IF. Our antibodies are suited to the varied requirements of these applications as they recognize both denatured and three-dimensional epitopes – giving them much higher affinity in your applications compared to peptide-generated antibodies. It is not just the science behind our antibodies that enables us to strive to be a better antibody company. To continually achieve and uphold this goal, we adhere to the following standards: we make and validate every single antibody that we sell, giving us complete control over production, quality, and distribution; because we maintain an up-to-date, worldwide inventory of our antibodies, we offer next day delivery to your lab if you order directly with us; and finally, we promise you, and all of our customers, a guaranteed refund if you are not satisfied with any of our antibodies.
