Figure 6From: A direct comparison of strategies for combinatorial RNA interferenceDirect comparison of the three co-RNAi strategies by retroviral delivery. (A) Northern blot analysis of total RNA extracted from DF-1 cells stably expressing single and double-gene targeting co-RNAi cassettes probed for sh-1a. (B) Normalised ratios of the Renilla:Firefly luciferase activity when DF-1 cells stably expressing single and double gene targeting co-RNAi cassettes were transfected with either psi-CHK-1 or psi-CHK-2. Values are shown as percentages of the negative control shRNA (sh-NS), as the mean of 4 replicates ± standard error.Back to article page
