A branched peptide is a type of peptide that contains multiple peptide chains that are connected to a central core. The central core is typically a branching point that connects the different peptide chains. Creative Peptides can produce branched peptide on lysine backbones or dendrimers as well as conjugation to carrier proteins (BSA / KLH / OVA ).

General Properties of Branched Peptides

  • Branched peptides are multivalent molecules with unambiguous chemical structure. The bulkier structure compared to that of the linear analogues gives them exceptional protease stability and therefore longer in vivo half-life.
  • Branched peptides, also known as peptide oligodendrimers, have proved stable to plasma proteases and peptidases and generally bind strongly to their target due to multivalent interactions.
  • Enhanced solubility compared to linear peptides.
  • Branched peptides also have unique binding properties and can be used as scaffolds.

Application of Branched Peptides

Drug development: Branched peptides can provide enhanced stability, solubility, and bioavailability compared to linear peptides, which can improve their therapeutic potential. They can also be designed to target specific receptors or enzymes, making them useful for the development of targeted therapies.

Vaccine development: By presenting multiple copies of an antigen on a branched peptide, it is possible to stimulate a stronger immune response than with a linear peptide.

Biomaterials: For example, branched peptides can self-assemble into nanofibers, which can be used as scaffolds for tissue engineering or drug delivery.

Diagnostics: Used as probes for imaging or diagnostic purposes. By attaching a fluorescent or radioactive label to a branched peptide, it is possible to visualize specific targets in vivo or in vitro.
