Isolation of Cowpea Mosaic Virus-Binding Peptides.

ABSTRACT: The plant virus cowpea mosaic virus (CPMV) is a natural nanocarrier that has been developed as a platform technology for the delivery of various payloads including peptide epitopes for vaccines, contrast agents for imaging, and drugs for therapy. Genetic fusion and chemical conjugations are the mainstay approaches to load the active ingredient to the exterior and/or interior of CPMV. However, these methods have limitations; genetic engineering is limited to biologics, and chemical alteration often requires multistep reactions with modification of both CPMV and the active ingredient. Either method can also result in particle instability. Therefore, to provide an alternate path toward CPMV functionalization, we report the isolation of peptides that specifically bind to CPMV, termed CPMV-bind
