Rat Monoclonal Antibodies

Prices for peptide synthesis

Absea provides antigenic peptides prediction from existing protein sequences free of charge. However, customers need to make the final decision. In addition, we do not guarantee that the peptide predicted will be immunogenic and antibodies raised against a peptide will recognize the native predicted protein.

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 and Table 2 below for peptide prices. Please see Table 3 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.

Discounts for multiple orders: 10-40 peptides (10% discount), 41 to 70 peptides (15% discount), 71 to 100 peptides (20% discount).
