At Proteintech, we produce every single antibody we sell; we do not rely on or supply to any other antibody providers: our products are unique and we are 100% accountable for each one. We realize this accountability by validating in-house, providing extensive technical support and guaranteeing your success: in addition to helping you troubleshoot your experiment, we will offer you a full cash refund if you are in any way dissatisfied. We can guarantee satisfaction because we have confidence in our products, confidence cultivated by the science behind our antibodies: we make them using as much of the native protein as possible, and purifying them using affinity purification with the original antigen. We carry out antibody production over a 102-day period, which allows for better antigen fitting to MHC molecules and affinity maturation in the host. This approach results in higher affinity antibodies with greater sensitivity, which you can use in any application and in multiple species.
You can only buy Proteintech antibodies directly from Proteintech or via one of its approved distributors — when you receive your antibody and see the Proteintech logo on the vial, know that you hold something that is truly unique.
