(A) Cellular distribution of BLOCK-iT Fluorescent Oligo in transfected RD cells. RD cells were transfected with different concentrations of BLOCK-iT Fluorescent Oligo and 2 μl of Lipofectamine 2000. At 24 h after transfection, the cells were observed under a fluorescence microscope. (B) RD cells transfected with BLOCK-iT Fluorescent Oligo were quantified with flow cytometry.
