Introducing Cell-Permeable Peptides (CPPs)

CPPs have the ability to enter the plasma membrane of a cell independent of a membrane receptor. They are usually small peptides 10–30 residues in length with positively charged amino acid sequences. We have a list of in-stock CPPs ready to conjugate with your targets. Your target can be a peptide, protein, fluorescent dye, or nanoparticle. Click for a full list of Cell Permeable Peptides.
