Specialist Vendors

Niche suppliers focusing on specific peptide classes, custom synthesis projects, or unique delivery technologies. Best for complex sequences and high-specification research requirements. Specialist vendors often differentiate through proprietary synthesis platforms including liquid-phase peptide synthesis (LPPS), continuous-flow SPPS, enzyme-assisted synthesis, or specialized conjugation chemistry for ADC payloads. Their capabilities frequently cover peptide-drug conjugates, cyclic peptides, fluorescently labeled peptides, PEGylated sequences, and peptide-mimetic scaffolds not available from general-purpose suppliers. Minimum order quantities and pricing reflect the higher complexity of these custom synthesis projects. Showing 7 listed suppliers.
