Polyarginines are well known for their ability to enhance cell penetration.
Other applications include the formation of PolyArg nanocapsules and the mediation of peptide–carbon nanotube interactions. Polyarginine also has been shown to inhibit protein aggregation. Whatever your desired application, Iris Biotech provides well-defined Polyarginines.
