Part of Proteintech Group's early vision was to make all its own products, to the highest standards possible, thus assuming ultimate responsibility for their quality. In addition to its founders' refusal to source a single antibody from any other provider, they also refused to supply any other provider. This approach would offer researchers many advantages, including a way of avoiding the same antibodies sold under different brand names by different companies – an unregulated practice that still continues within the industry.

Ultimately, the 'Original Manufacturer' approach laid out by Proteintech's founders would contribute to an increasing sense of accountability in the antibody industry.


One of its original founders and current
CEO Dr. Jason Li 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."
