Arginine-rich cell-penetrating peptides.
Arginine-rich cell-penetrating peptides are short cationic peptides capable of traversing the plasma membranes of eukaryotic cells. While successful intracellular delivery of many biologically active macromolecules has been accomplished using these peptides, their mechanisms of cell entry are still under investigation. Recent dialogue has centered on a debate over the roles that direct transloc...
متن کاملCell Penetrating Peptides
During the last ten years it has been observed that a number of peptides and proteins are able to penetrate the cell membrane and enter the cell. Furthermore, it has been shown that even many cargo molecules that are covalently attached to these peptides will be translocated into the cell. Peptides that show the ability to translocate through the cell membrane are usually short peptides of less...
متن کاملEnhanced cell penetration of acid-degradable particles functionalized with cell-penetrating peptides.
Biopharmaceuticals, such as proteins and DNA, have demonstrated their potential to prevent and cure diseases. The success of such therapeutic agents hinges upon their ability to cross complex barriers in the body and reach their target intact. In order to reap the full benefits of these therapeutic agents, a delivery vehicle capable of delivering cargo to all cell types, both phagocytic and non...
متن کاملBiotinylated Cell-penetrating Peptides to Study Intracellular Protein-protein Interactions
Here we present a protocol to study intracellular protein-protein interactions that is based on the widely used biotin-avidin pull-down system. The modification presented includes the combination of this technique with cell-penetrating sequences. We propose to design cell-penetrating baits that can be incubated with living cells instead of cell lysates and therefore the interactions found will ...
متن کاملIntracellular Delivery of Histidine and Arginine Rich Cell Penetrating Peptides into HeLa cell Line
Most bioactive macromolecules, such as DNA and RNA, cannot permeate into cells freely from outside the plasma membrane. Cell penetrating peptides are a group of short peptide sequences that are able to transverse the cell membrane for mediating gene into living cells. In this study we demonstrate two cell penetrating peptides 5H-R9-C and 7H-R9-7H-C. These peptides are synthesized by solid phase...
