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 ).
Tetrabranched peptide (Jlenia Brunetti, et al. 2018)
|(KKIRVRLSA)4K2K-βala||Antimicrobial peptide||Activity against different multidrug resistant Gram-negative bacteria; anti-inflammatory effects in vitro and in vivo|

|(KCCYSL)NH2||Antitumor activity of liposomes decorated with P6.1 peptide||Activity as target-selective delivery system to cancer cells overexpressing human epidermal growth factor receptor-2|
|Reducible branched cationic polypeptide (RBCP)||Antitumor activity of a dual sensitive branched codelivery system RHD/p53||In vitro and in vivo studies indicated that the system RHD/p53 could enhance antitumor efficacy, which provides a useful strategy for co-delivery of different therapeutic agents in tumor treatment|
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.
