The preparation and characterization of two novel LysB29 selectively labelled fluorescent derivatives of human insulin are described. Two probes were chosen: 4-chloro-7-nitrobenz-2-oxa-1,3-diazole (NBD) and 7-methoxycoumarin-4-acetic acid (MCA), which have a relatively small, compact structure and are able to react with

Cell-penetrating peptides constitute efficient delivery vectors, and studies of their uptake and mechanism of translocation typically involve fluorophore-labeled conjugates. In the present study, the influence of a number of specific fluorophores on the physico-chemical properties and uptake-related characteristics of penetratin
