    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.
