Our Peptide Synthesis Process:
Peptide Synthesis Capabilities
- Peptides from 5 to 100 amino acids
- Scales from milligram to grams
- Purities from crude to >98%
- Fast, on-time delivery
HPLC Purification
- >70% is typically considered immunograde and is suitable for producing polyclonal antibodies. However, HPLC purification to >90% is recommended for peptides with modified amino acids and for monoclonal antibody development. ProSci can provide peptides from crude to >98% purity.
Standard Synthesis
- 20 mg at >70% purity (11-25 amino acids long)
Peptide Conjugation
- Peptide conjugation is available to the following carrier proteins: KLH, BSA, or OVA.
ProSci is the preferred partner for peptide synthesis and conjugation services. Our years of antibody expertise, service offerings, and investment in your success provides antibody solutions as if we were an extension of your lab.
