Optimizing your immunofluorescence protocol

Introduction to Proteintech

Proteintech has been the original manufacturer of antibodies, ELISA kits, and proteins since 2002. We recently became ISO accredited, which means that we can manufacture GMP grade cytokines and growth factors for use in cell and gene therapies. We have five global inventory sites, and all of our products are in stock and available for next day delivery.

Proteintech has polyclonal and monoclonal antibodies against 13,000 targets and within that, 2,500 targets have been validated in KO/KD validation. This is the broadest coverage of knockdown/knockout validated antibodies in the antibody industry. This year, we launched our CoraLite fluorescent-dye antibodies for use in direct immunofluorescence and protein ladders for use in Westen blots (WB).

The main difference between Proteintech and other antibody manufacturers is that we supply and make every product ourselves and you can only buy our products with our label on it. So by cutting out the middleman, we are not allowing anyone else to sell our products under their label so we offer you as the customer complete transparency. This means more lot-to-lot consistency because we can guarantee supply in addition to our huge library of original validation data direct from the lab with complete control over the quality of our antibodies, making sure it works in your hands. We also offer the opportunity for you to reserve your favorite polyclonal lot to ensure that you have future supply. 

As a company, we measure our success by your scientific success specifically helping you publish impactful research faster. This graph shows that over our company history, our products are featuring in more and more publications each year. As of today, we have over 70,000 publications citations.
