Click pVec – Click Peptides

pVEC is an amphipathic cell-penetrating peptide (CPP). This CPP is derived from murine vascular endothelial cadherin, which is able to cross the blood brain barrier. pVec can permeate cell membrane at low micromolar concentration and mostly localising to the nucleus but is also found throughout the cell. Importantly, pVec shows efficient cellular uptake when carrying large molecular cargo making it a highly potent transporter for drug delivery. pVec is provided here with a N-terminal alkyne attachment. Two of the most regularly encountered functional groups for click chemistry are azides and alkynes, and the azide-alkyne cycloaddition has become the most popular click reaction. The use of click chemistry with alkyne-pVec allows a wide variety of applications particularly for conjugation, modification, and peptide design.
