Peptide synthesis

Absea subcontracts peptide synthesis to peptide companies in China. The quality of peptide is judged by HPLC and mass spectroscopy. Synthesis will take 2 - 3 weeks for peptides less than 20 residues and 3 - 4 weeks for peptides having 21 to 30 residues.


Please see Table 1 below for peptide prices. Please see Table 2 below for additional charges for modified residues. To make monoclonal or polyclonal antibodies, we suggest you make 10 mg peptide at 90% purity. If you want to affinity purify antibodies using the peptide cross-linked beads, we suggest you make 20 mg peptide.
