We are the Peptide Experts!

Tailored Peptide Synthesis for Every Application


Over the last 20 years, we have developed a unique and very broad expertise in peptide manufacturing and have pioneered patented technologies in the field of peptide libraries, pools and microarrays as well as micro-scale synthesis. 

Our offering ranges from micro-scale synthesis (10 - 50 nmol) to intermediate peptide synthesis (1 – 100 mg) with high throughput capacities for tens of thousands of peptides per month. Select your peptide format (pool, library, microarray...), peptide purity (from crude up to >98%) and optional modifications (phospho, biotin, dyes and labeld, cyclization, conjugation, stable-isotope labeling etc.).

Our state-of-the-art laboratories are located in Berlin, Germany and JPT operates according to the latest ISO 9001:2015 regulations.


Custom Peptide Synthesis


Our Quality Guarantee

Since 2004, JPT has maintained an active quality management system that is reviewed, audited and certified annually by an independent certification body (TÜV Rheinland) to ISO 9001 standards. This includes full process documentation and an early warning system in case of problems.

Neo-Epitope Discovery & Therapy

Neo-Epitope Discovery & Therapy

Neo-epitopes are important targets for individualized cancer immunotherapy. JPT’s high-throughput peptide techniques enable access to customized peptide products for neo-epitope prioritization and validation, individualized therapy development and immune monitoring. Learn more
Proteomics

Proteomics

Proteomics is the study of a cell's protein inventory at different times by protein identification and quantification. The application of mass spectrometry and more specifically LC-MS/MS has tremendously facilitated this process. JPT developed proprietary approaches for the provision of quantified custom peptides and ready-to-use products enabling protein biomarker identification and quantitation. Learn more
COVID-19

COVID-19

JPT was the first company responding to the Covid-19 pandemic with the launch of a broad SARS CoV-2 genome spanning portfolio of peptide tools. The ready to use and custom peptide tools include antigen spanning PepMixTM peptide pools and PepStarTM peptide microarrays of SARS-CoV-2 wild type and mutated antigen sequences as well as antigens from other relevant corona viruses.  Learn more
