About quartett

We are Quartett — a Berlin-based biotech company combining family values with scientific excellence to advance cancer diagnostics.

Excellence in biotechnology — made in Germany

Founded 1986 in Berlin/Germany as a family-run biotechnology company quartett is committed to the 
fight against cancer and wants to contribute better cancer diagnosis. Specialized in two areas, we produce monoclonal antibodies for anatomic pathology/IHC, as well as synthetic peptides for the pharmaceutical industry and research.

Our first manufacturing site was founded in 1997. In 2023, we moved into our new company building including an area of 800 sqm laboratory space. Our certified production site (ISO 9001, ISO 13485, IVDR) guarantees products of highest quality. All products are solely developed and manufactured in Germany.

Our business areas

Quartett develops high-quality antibodies, detection systems,
and reagents for reliable and precise diagnostic applications.
Explore our main product categories below.

Biochemicals

The company has specialized its product portfolio in the production and modification of synthetic peptides with an HPLC purity of over 95% (protease inhibitors, peptides for antibody production). 

The success of our purely synthetic peptides enabled us to develop a new technology for producing recombinant monoclonal rabbit antibodies.

Anatomical Pathology

Our second area of expertise is the production of monoclonal rabbit and mouse antibodies for anatomical pathology, as well as the development of IHC accessory reagents optimized for all automated staining platforms and manual applications. With our innovative method for producing recombinant monoclonal rabbit antibodies, we are one of the few companies worldwide capable of doing so. Normally, almost all antibodies are produced using mice, but the immune system of a rabbit is far superior.
This allows us to create highly sensitive and specific antibodies that are valuable tools in cancer diagnostics.
