Translocation across the membrane into cells is possible for certain peptides and proteins. To investigate the structural requirements of β-peptides for this process, a series of fluorescein-labeled β-peptides has been synthesized and their cellular uptake into 3T3 mouse fibroblast cells determined by fluorescence microscopy (see picture). Polycationic β-peptides have been shown to internalize into cells, and accumulation in the cytosol and nucleus is observed.
