Frequently Asked Questions
What is your minimum order quantity?
There is no fixed minimum. We accommodate orders from milligram-scale research quantities to multi-kilogram production batches.
How long does custom peptide synthesis take?
Typical turnaround is 2–3 weeks for standard linear peptides. Complex sequences or specialized modifications may require 4–6 weeks. Rush service is available.
What purity levels do you offer?
Crude (50–70%), desalted (>75%), >90%, >95%, and >98%. All purified peptides verified by HPLC and LC-MS with a Certificate of Analysis.
Can you handle unusual modifications?
Yes. With 400+ validated methods, we routinely handle phosphorylation, biotinylation, PEGylation, cyclization, stapling, fluorescent labeling, FRET pairs, and unnatural amino acids.
Do you ship internationally?
Yes — to 30+ countries. Lyophilized format is standard for stability. Cold-chain shipping available for temperature-sensitive products.
How do I request a quote?
