Founded as a family-run company in 1986, quartett ensures for more than 30 years consistent quality of products. In 1997 we established our production site, which is certified according to EN ISO 9001:2015 and EN ISO 13485:2016. Our quality management system guarantees products of highest quality.

The company specialized its product profile in manufacturing and modification of synthetic peptides – also on customer request – with a HPLC purity higher than 95 %. This includes protease inhibitors or peptides for antibody production. Furthermore, we offer peptide analytic services with qualitative and quantitative analysis of amino acids.

Second expertise is the production of a variety of reagents for histology, cytology and IHC including client-oriented production, IHC contract work as well as the production of monoclonal and polyclonal antibodies. This includes our new line of rabbit and mouse monoclonal ‘Q clone’ antibodies.

All products are exclusively manufactured in Germany without outsourcing any production step. Nowadays, we expand into all other diagnostic and research fields and supply our customers in universities, government institutes, pharmaceutical and biotechnological companies, hospitals and private doctor offices.
