Characterization of interaction between DNA and 4',6-diamidino-2-phenylindole by optical spectroscopy.
We have examined the interaction between 4',6-diamidino-2-phenylindole (DAPI) and DNA using flow linear dichroism (LD), circular dichroism (CD), and fluorescence techniques. We show the presence of… Expand

Kinetics for hybridization of peptide nucleic acids (PNA) with DNA and RNA studied with the BIAcore technique.
The binding of a mixed-sequence pentadecamer PNA (peptide nucleic acid) containing all four nucleobases to the fully complementary as well as various singly mismatched RNA and DNA oligonucleotides… Expand

Uptake of analogs of penetratin, Tat(48-60) and oligoarginine in live cells.
Cell-penetrating peptides are regarded as promising vectors for intracellular delivery of large, hydrophilic molecules, but their mechanism of uptake is poorly understood. Since it has now been… Expand

Application of a novel analysis to measure the binding of the membrane-translocating peptide penetratin to negatively charged liposomes.
The binding of penetratin, a peptide that has been found useful for cellular delivery of large hydrophilic molecules, to negatively charged vesicles was investigated. The surface charge density of… Expand

Effects of tryptophan content and backbone spacing on the uptake efficiency of cell-penetrating peptides.
Cell-penetrating peptides (CPPs) are able to traverse cellular membranes and deliver macromolecular cargo. Uptake occurs through both endocytotic and nonendocytotic pathways, but the molecular… Expand

Stimulated endocytosis in penetratin uptake: effect of arginine and lysine.
Cell-penetrating peptides can deliver macromolecular cargo into cells and show promise as vectors for intracellular drug delivery. Internalization occurs predominantly via endocytosis, but the exact… Expand
