Fig. 2. Nuclease resistance of GROs. (A) Denaturing-polyacrylamide gel (20%) electrophoresis assay of 5′-fluorescein-labeled GROs (10 μM) after incubated in RPMI 1640 medium with 10% FBS at 37 °C for different time, gels were exposed under UV light and photographed. (B) Degradation curves of GROs, data were extracted from A.
