Custom peptide synthesis is the specialized manufacturing of peptide sequences tailored to specific research, therapeutic, or diagnostic applications. Using solid-phase peptide synthesis (SPPS) technology, our service delivers high-purity peptides (up to 98%+) with precise amino acid sequences, lengths from 5 to 100+ residues, and a wide range of modifications including phosphorylation, cyclization, biotinylation, and fluorescent labeling. Whether you need custom peptides for antibody production, enzyme studies, vaccine development, or drug discovery, our GMP-compliant facility ensures rapid turnaround, rigorous quality control (HPLC and mass spectrometry), and scalable quantities from milligrams to kilograms.
