Proteintech’s move follows 20 years of strong and consistent growth at the company. Proteintech last expanded its headquarters just five years ago and expects to see growth continue amid demand for its antibodies, ELISA kits and protein products, according to Jeff Lee, Chief Operating Officer. In the past two years the company’s headcount has doubled to 300 employees and expects it to double again in two years.

“It’s a big year for Proteintech with it being our 20th year in business, receiving our 100,000th citation of our products in scientific publications, and expanding but we wouldn’t have this company or any of its successes without our people,” said CEO Dr. Jason Li. “Every step our employees took have made this company what it is today. They have made our company strong.”

“The 100,000 citations we’ve received over the years is a contributing factor to our expansion. The consistent growth of citations from researchers using our products is a direct reflection on the value that researchers place on the consistent quality and reproducibility of our products correlating with the growth we’ve seen,” said Dr. Deepa Shankar, Chief Scientific Officer.

The new headquarters will also house expanding operations for Proteintech’s North American distribution, R&D, finance, logistics, customer support, and IT.
