Custom Peptide Synthesis Service

PROCOMCURE Biotech offers a variety of custom tailored peptides for you. This also includes “hard to make” peptides, various modifications and also peptides labeled with isotopes for NMR work.


Scale and Purity

Depending on your application(s), our labs produce peptides on a milligram (mg) to gram (g) scale, and with different purities.  All synthesized peptides are validated by both HPLC and mass spectroscopy.


PuritySuitable Applications
>75%antigens (polyclonals), antibody purification (polyclonals), ELISA
>85%antigens (polyclonals), antibody purification (polyclonals), ELISA, quantitative biochemical and enzymatic assays, affinity purification, cell attachment, Western blotting, electrophoresis
>95%antigens (monoclonals), quantitative biochemical assays (receptor binding, competitive binding, phosphorylation, proteolysis, enzymatic inhibition), structural biology, NMR, mass spec, other in vitro or in vivo studies
>98%pharmaceuticals, cosmetics, SAR, X-ray crystallography


Difficult Synthesis

So called “hard to make” peptides rich in proline- or glycine residues, highly hydrophobic or highly charged ones as well as long peptides (>40 amino acids) can be synthesized.
