Mission

Our Mission

ChromoTek’s mission is to support extraordinary discoveries with high performing Nanobody-based affinity reagents in proteomics and cell biology. We strive to improve, accelerate, and simplify our customers’ research around the world.

New tools for better research

ChromoTek pioneered the development and commercialization of Nanobody-based research reagents. ChromoTek created 2008 a missing link reagent between cell biology and proteomic applications, when it introduced the GFP-Trap® for immunoprecipitation. The outstanding performance of GFP-Trap drove the adoption of GFP as protein tag in biochemical applications.

We are utilizing the unique advantages of Nanobodies over conventional antibodies to develop new tools for better research:

  • Nano-Traps affinity resins
  • Nano-Booster and Nano-Label Nanobody dye conjugates
  • Proprietary Chromobody® nanoprobes for live cell imaging
  • Spot versatile capture and detection system

 

Proteintech Acquires ChromoTek, Expanding its Next Generation Antibody Tools

Chicago and Munich — October 15, 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 common 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.”
