Custom peptide synthesis
Giotto Biotech can syntesize peptides up to 150 AA and offers a wide range of peptide modifications.
Your project is our priority so we will start from the beginning until we get the right peptide.
WHAT INCLUDES OUR PEPTIDE SYNTHESIS SERVICE ?
Our peptide synthesis service includes the lyophilized peptide and a QC report. The QC report includes:
- Amino acid sequence
- Modification information
- Peptide purity
- Mass spectrum
- HPLC
WHICH PURITY GRADE SHOULD I CHOOSE FOR MY PEPTIDE SYNTHESIS ?
Peptide synthesis purity grade can have an important impact on the price. However, it can also be critical for the success of your experiments. Therefore, we provide a table summarizing the peptide purity grade requested for several applications:
| Peptide purity grade | Applications |
| crude | Interaction studies (ligand-receptor, protein-protein…) Mutation screening Sequence optimization |
| >70% | Polyclonal antibody production ELISA assays |
| >80% | Monoclonal antibody production In vitro tests In vivo studies Quantitative inhibition studies Quantitative interaction studies NMR studies |
| >95% | Clinical trials Crystallography Quantitative studies |
If your application is not mentioned in the table, please contact us. We will be glad to help you choose the most relevant peptide purity grade!
