Conjugation
Conjugation — The covalent attachment of one molecule to another, such as linking a peptide to PEG, a fatty acid, or a fluorescent dye to alter its properties.
What Is Conjugation?
Conjugation is the covalent attachment of a peptide to another molecule (polymer, lipid, drug, fluorophore, carrier protein, nanoparticle) to modify its properties. Conjugation is one of the most powerful tools in peptide drug design, enabling half-life extension, targeted delivery, and multimodal functionality.
Conjugation Types
- PEG: Increases hydrodynamic size, reduces renal clearance
- Fatty acid: Albumin binding for extended circulation (semaglutide model)
- ADC payloads: Cytotoxic peptides conjugated to targeting antibodies
- Fluorophores: Imaging and binding assay applications
