Custom Peptide Synthesis

JPT's peptide production has a substantial, long-standing expertise in custom peptide synthesis services, providing custom peptides with highest quality for even complex or unusual peptide sequences. If you would like to order a quality peptide synthesis  using regulated processes, choose JPT!

Furthermore, our peptide synthesis service has a very high success rate (over 99%) as JPT has developed the know-how to choose and optimize the appropriate peptide synthesis method for each peptide. We go the extra mile to get your custom peptides done!

Custom Peptide Synthesis Service:

  • Tailored peptides manufactured on demand
  • Dedicated peptide production (peptide synthesis and peptide purification) labs
  • State of the art equipment
  • Highest environmental and health standards. 
  • Skilled customer support
  • We help with the selection of peptide specifications (peptide purity and amount, peptide modifications, analytical options and peptide delivery formats).

Peptide Synthesis Quality Control:
After peptide synthesis, each peptide is routinely analyzed by LC-MS, MALDI-MS or HPLC to confirm the identity and quality of your custom peptide. Optional peptide analyses can be ordered with each synthesis of peptides and include:

For further QC/QA options in clinical applications and custom peptide synthesis under Clinical Grade conditions please check our Clinical Peptides page.

Custom 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 much more. For detailed information on peptide synthesis of modified peptides please visit our Peptide Modifications & Specialty Peptides  and our PTMs (Post-Translational Modifications) pages. 

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:

Please contact our customer support or visit our Specialty Peptides page for detailed information.

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, 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

What is a peptide?

A peptide is a molecule of amino acids (aa) linked via a peptide bond. In biology, peptides and proteins (from approx. 51 aa) are distinguished by amino acid length. Peptides and proteins occur in biology in many forms such as dipeptides, cyclic peptides or phosphopeptides, and can be analysed by sequencing, quantification, NMR and many other methods.

Quality Assurance

All production is performed according to ISO 9001:2015 standards
