What is the maximum peptide length you can synthesize?

We routinely synthesize peptides up to 80 amino acids. Longer sequences are evaluated case-by-case using fragment coupling strategies.

What purity grades are available?

Standard grades are >85%, >95%, and >98% by HPLC. We provide chromatograms and MS data with every shipment.

Can you synthesize difficult sequences?

Yes. We use pseudoproline dipeptides, Dmb protection, and specialized resins for sequences with aggregation-prone regions or multiple hydrophobic residues.
