Custom Peptide Synthesis Services
Crefu Peptides is a full service peptide company. Solid phase peptide synthesis, solution phase and microwave synthesis
chemistry are used to prepare your desired custom peptide product.
We use preparative HPLC to purify the desired peak, and the final peptide sample is analyzed again by reverse phase HPLC
to verify purity. Mass spectrometry is used to verify the mass of the peptide. HNMR analysis report to confirm special small
compounds-peptide complex.
