Nanobio Delivery is pleased to offer the best customized RNA nanoparticles with large scale and high purity. The RNA nanoparticles can be designed with desired modifications on backbones or bases (e.g. 2'O-Methyl, 2'-Fluoro, thioates, etc.), or with decorations (biotin, streptavidin, fluorophores, etc.). 3WJ from pRNA of phi29 DNA packaging motor had been proved to be an ideal scaffold for building therapeutic RNA nanoparticles with its high thermodynamical stability and ideal size for chemical synthesis, various pRNA 3WJ derived multivalent scaffolds have been developed for customers' choice.
