Proteintech Acquires ChromoTek, Expanding its Next Generation Antibody Tools

Chicago and Munich - October 20, 2020 - Proteintech, the benchmark in antibodies, today announces the acquisition of ChromoTek, a manufacturer of Camelid, single-domain antibodies, also known as nanobodies. ChromoTek is the market leader in nanobodies - high-performance recombinant reagents used for breakthrough research discoveries. The combined companies will better address the industry's growing opportunities and challenges in single cell analysis, super resolution imaging, and multiplex assays.

"Our fit-for-purpose nanobody-based tools perfectly complement the comprehensive antibody coverage of the proteome that Proteintech offers," said Dr. Marion Jung, CEO of ChromoTek. "It is exciting to be working together with a company that shares our values in reproducibility and quality for the benefit of research and beyond." Dr. Jason Li, CEO of Proteintech, said, "This new partnership will deliver considerable value to the market. With global manufacturing across three continents, not only will we serve the research market better, but we'll also deeply impact translational science and therapeutic applications."

ChromoTek GmbH is located in the Biotechnology Innovation and Start-up Center in Martinsried near Munich and has become the leading manufacturer of alpaca nanobodies. The biotech start-up had the vision to improve, accelerate and simplify the research of its customers around the world. "I am very proud that Dr. Marion Jung, Managing Director of ChromoTek GmbH, has achieved this goal and will now serve a global market from Bavaria through the cooperation with Proteintech", said Dr. Peter Hanns Zobel, Managing Director of the IZB.

About the Innovation and Start-up Center Biotechnology (IZB):

The company IZB mbH, founded in 1995, is the operating company of the Innovation and Start-Up Centers for Biotechnology in Planegg-Martinsried and Freising-Weihenstephan, and has developed into one of the top ten renowned biotechnology centers in the world. More than 50 biotech companies with more than 600 employees are currently located on an area covering 26,000 m2. This is where work focuses on developing drugs against the most severe diseases such as cancer, Alzheimer's disease and various autoimmune diseases - and there are already many successes. At the IZB Freising-Weihenstephan - 15 minutes from the airport - scientists are working on developments in the field of life sciences. An essential criterion for the success of the IZBs is the proximity to top research on the Martinsried/Grosshadern Campus. The new infrastructure measures, such as the Faculty Club G2B (Gateway to Biotech), the IZB Residence CAMPUS AT HOME, the Chemistry College Elhardt, the two kindergartens BioKids and BioKids2, as well as the two restaurants SEVEN AND MORE and Café Freshmaker, have become decisive location factors. Successful companies that have emerged from the IZB include, for example, Medigene AG, Morphosys AG, Micromet GmbH (now Amgen AG), Octopharma GmbH and Corimmun (today Janssen-Cilag).
