Custom Peptide Synthesis
Our custom peptide synthesis service offers several options for the synthesis of peptides of 2–110 amino acid residues by automated microwave-assisted solid-phase peptide synthesis (MW-SPPS) technology using standard Fmoc chemistry.
We synthesize customer-defined peptides with complex modifications (e.g., phosphorylation, methylation, PEGylation, glycosylation, biotinylation, cyclization, incorporation of D-amino acids, etc.), labelled peptides, lipopeptides, peptidomimetics, and peptide libraries according to our customer's requirements.
Our portfolio also includes modified ubiquitin variants, β-amyloid peptides, cell-penetrating peptides (CPPs), and other specific peptides used in antibody production, proteomics, cutting-edge research in medicine/life science, drug discovery, and in vitro diagnostics programs.
Our peptide synthesis scales range from milligrams to multi-gram quantities and are highly purified (≥ 98% by HPLC) and supplied as trifluoroacetate (TFA) salts unless otherwise stated. Our analytical service provides comprehensive quality control (QC) reports, including RP-HPLC and mass spectrometry (MS) analysis, to confirm the purity and identity of the desired peptide products.
Polypure offers the best possible solution for customer peptides with the best equipped technology, with high quality solutions and with many options for modifications, purity levels and formats to meet customer needs.
We are producing a variety of peptides – from simple to long and challenging sequences per our customers’ specifications.
On request, we also offer quantitative Amino Acid Analysis (qAAA) as an additional service to determine the relative amino acid composition and individual free amino acids in your protein/peptide samples.
- Peptides with various degrees of purity from crude to >98%
- Peptides with different amounts: mg, g or kg scale on request
- Large peptides: up to 100 amino acids
We promise you products of the best quality and with short delivery times, trust is the basis of our cooperation.
Most custom peptides can be shipped within 2-3 weeks of receiving an official order. Full confidentiality of all peptide synthesis orders is assured.
Our highly skilled chemists are happy to provide you with a cost-effective solution to advance your research or to meet your specific applications.
If we fail, you don't have to pay anything.
