Tailored Peptide Synthesis for Every Application

Tailored Synthesis

Custom Peptide Synthesis


Select your peptide format (pool, library, microarray...), peptide purity (from crude up to >95%) and optional modifications (phosphorylation, biotin, dyes and labeled, cyclization, conjugation, stable-isotope labeling, etc.).


Tailored Synthesis

Scalable Peptide Solutions


Our product range includes micro-scale synthesis (10-50 nmol), intermediate peptide synthesis (1-100 mg), and large-scale peptide synthesis (>1 g).


Tailored Synthesis

Years of Experience


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.

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.

"As Director of the Protein Profiling at Yale Keck Biotechnology Resource Facility, I coordinated a collaboration between the Association of Biomolecular Resource Facilities (ABRF) standard proteomic research group (sPRG) and JPT Peptide Technologies to develop the ABRF cross-species SpikeMix™ Peptide Pool. The joint development turned out to be an extraordinary effective endeavor and the resulting product was qualified in more than 52 proteomics labs around the globe. I was impressed by JPT's scientific and technological capabilities as well as their enthusiasm to drive the project forward."
