Custom Peptide Synthesis

JPT has substantial and long-standing expertise in peptide synthesis. We provide the highest quality custom peptides, no matter how complex or unusual the peptide sequences. If you would like to order a high quality peptide synthesis service using regulated processes, choose JPT!
Because JPT has developed the know-how, our peptide synthesis service has an extraordinary success rate of over 99%. We go the extra mile to customize a peptide specification that fits your application best!

Peptide Synthesis Service

  • Tailored peptides manufactured according to ISO 9001:2015 standards
  • Research and Clinical Grade Peptide synthesis available
  • Dedicated peptide production (peptide synthesis and peptide purification) labs
  • State-of-the-art equipment and highly trained opeptide synthesis personnel
  • Complying with highest environmental, health and ethical standards
  • Scientific customer support trained in peptide applications
  • Help with the selection of peptide specifications from research to clinical applications

Peptide Synthesis Quality Control

After peptide synthesis, each peptide is routinely analyzed by LC-MS, MALDI-MS or HPLC to confirm the identity and purity of your custom peptide. Optional peptide analyses can be ordered with each synthesis of peptides which include:
  • AAA (amino acid analysis)
  • Peptide sequence analysis (mass spectrometry)
  • Residual solvent determination and water determination
  • Solubility testing or stability testing
  • Toxicity, sterility, endotoxin, bioburden testing
  • NMR (nuclear magnetic resonance)
  • and many more
For further QC/QA options for clinical applications please check our Clinical Grade Peptides.

Peptide Synthesis of Special & Modified Peptides

JPT also has vast experience in designing and producing tailored peptides with modifications such as fluorescence labels, biotinylation, alkylation, glycosylation, phosphorylation and  more. For detailed information on peptide synthesis of modified peptides please visit Peptide Modifications & Specialty Peptides and Post-Translational Modifications

Modifications & Labels for Custom Peptide Synthesis

We offer all common peptide modifications, labels and tags and are comitted to synthesize even the most challenging peptides. Peptide synthesis options include, but are not limited to the following:

QC/QA for Peptide Synthesis

JPT provides a comprehensive analytical datasheet and corresponding raw data as documentation with your custom peptides. The documentation is carefully double checked and archived before leaving JPT’s production facilities in Berlin.
Our standard quality control includes LC-MS with ion trap, quadrupole or TOF detection, MALDI-MS or HPLC.
We offer a large variety of optional Peptide Analysis Services such as Stability Testing, Peptide Content Determination, or Cell Toxicity Testing.

Testimonials for Custom Peptide Synthesis

"The RV 144 HIV trial is considered as one of first successful HIV vaccine trials. It has become clear that the V2 loop of gp120 is an important site for immunogenicity and protection from HIV infection. The use of JPT's PepStar™ microarray technology has been very useful for the correlation of the clincial outcome with humoral immune responses. As have the cyclic peptides been from JPT to validate these findings!"
J. Currier, PhD, Walter Reed Army Institute of Research, Rockville, Maryland, USA

"Our research relies heavily on developing robust high-throughput screens with fluorescent peptides. We have found that JPT’s are the best on the market because the signal-to-noise ratio is very high, providing the sensitivity we need for the screens. Their peptides always perform well. In addition, the knowledge, wonderful customer support, and fast turnaround time provided by JPT have been invaluable in helping us develop the best peptides for our assays."
Prof. Carla Koehler, UCLA, Los Angeles, CA
