WebWe recently demonstrated that an impermeable fluoresceinated pentapeptide enters the cytoplasm and nucleus of COS 7 cells in the presence of a host-[2]rotaxane by a mechanism that does not depend on an active cell-mediated process. WebThe locked rotaxane exhibited a reduced capacity to transport a fluoresceinated peptide into cells, whereas the unmodified rotaxane efficiently delivers the peptide. Flow cytometry experiments demonstrated that a high percentage of the cells contained the delivered peptide (89−98%), the level of delivery is concentration dependent, and the ... how many missions are in cod waw

WebDec 1, 2002 · The synthetic peptides were labeled using a fluorescein amine (FS) labeling kit (Panvera, Madison, WI). The labeling reagent is a succinimidyl ester of fluorescein, which selectively forms an amide bond with N-terminal amino group of peptides or proteins at neutral pH; this reagent reacts more rapidly and forms a more stable derivative than FITC. WebWe have compared the kinetics of the responses of neutrophils to the kinetics of ligand-receptor interaction and internalization, using as a model ligand the fluoresceinated hexapeptide N-CHO-Nle-Leu-Phe-Nle-Tyr-Lys-Fluorescein (Nle, norleucine).
