Cell penetrating peptides (CPPs) can facilitate the entry of molecules into cells. They are able to deliver cargoes such as small molecules, nucleic acids or proteins into cells. CPPs are usually polycationic or amphipathic and have the ability to cross the cell membrane, thereby delivering various molecular cargoes into the cytoplasm or organelles. We offer a range of off-the-shelf CPPs with fast delivery and high quality. If you require a custom solution, explore our custom peptide synthesis services.
