Proteintech Group: For Scientists, By Scientists

Proteintech Group was founded in 2001 by a group of scientists, who were actively engaged in NIH funded research at the time. One of the original founders and current CEO Dr. Jason Li was an Associate Professor of Immunology at the University of Illinois at Chicago during the company's foundation years. He says of the reasons behind Proteintech's establishment:

"AT THE HEART OF OUR ASPIRATION WAS A COMPANY FOR SCIENTISTS BY SCIENTISTS; AN ANTIBODY PROVIDER THAT WOULD OFFER RESEARCHERS THE ADVANTAGE — NOT INVESTORS."

As a company founded by scientists, Proteintech Group recognises the tireless efforts and sacrifices made by researchers to advance scientific discovery. Proteintech aims to match its’ customers’ dedication to research by providing high quality, reliable reagents that contribute to reproducible results.
