Objective: To overcome drawbacks of cell-penetrating peptide (CPP)-conjugated forms, namely instability against attack by proteases, and binding to serum proteins that lowers the availability of the CPP to target cells.
Summary: Complexes were prepared by combining biotinylated CPPs with Streptavidin-ZAP to evaluate the impact of utilizing a rigid collagen-like triple-helical scaffold to improve CPP performance. There was low adsorption onto serum proteins and triple-helical CPPs are extremely stable in animal serum. Such unique properties are expected to be advantageous to long-term applications in cell culture systems and to in vivo drug delivery.
Usage: Biotinylated CPPs were interacted with Streptavidin-ZAP (SA-ZAP); IT-27: Streptavidin-ZAP
