Bioconjugate
Bioconjugate — A compound formed by covalently linking a biomolecule such as a peptide to another entity like a drug, fluorophore, or polymer.
What Is a Bioconjugate?
A bioconjugate is a molecule created by covalently linking a peptide to another biomolecule or synthetic entity. Bioconjugation combines the biological recognition properties of the peptide with desired properties of the conjugation partner: polymer (PEG) for half-life extension, fluorophore for imaging, drug for targeted delivery, or nanoparticle for formulation.
Bioconjugate Types
- Peptide-PEG: PEGylated peptides with extended circulation time
- Peptide-drug: Tumor-targeting peptide linked to cytotoxic payload
- Peptide-fluorophore: Labeled peptides for binding assays, imaging, and cellular uptake studies
- Peptide-lipid: Lipidated peptides for albumin binding (semaglutide model)
- Peptide-antibody: Peptide payloads on antibodies for bispecific targeting
