Epifluorescence microscopy study of FITC-antisense oligodeoxynucleotides (AsODN) cellular distribution. Cytoplasmic distribution of fluorescein green fluorescence (right images) was demonstrated after 4-hour incubation with either free AsODN (a, b), liposomal AsODN (c, d), cineole-treated free AsODN (b), and cineole-treated liposomal AsODN (d). Left images illustrate DAPI-stained nucleuses of the same systems.
