Figure 6. Hammerhead Spiegelzyme stability analysis in COS-7 cells.

Figure 6

A. 5′-fluorescein-labelled Spiegelzyme (1 µg) was transfected into cells with Lipofectamine 2000. The microscope images were taken at 24, 72, 96, and 120 h after transfection. B. The RNA isolated from transfected cells (Trizol, Ambion) was analysed on 20% PAGE with 7 M urea. Lane 1 control hammerhead Spiegelzyme. Spiegelzyme after 120 h of incubation in COS-7 cells (lane 2).
