Rescue of SH-SY5Y cells by RNA-interference. Normalised cell counts (in % of untransfected control) of SH-SY5Y transfected with plasmids encoding a fusion protein between HCR-NTPase and RFP alone (HCR-NTPase-RFP) or cotransfected with siRNA1, siRNA2, siRNA3, and siRNA4, respectively. Compared to the control, less than 1% of cells containing the HCR-NTPase-RFP fusion protein could be detected by fluorescence microscopy (data not shown). The data for the GFP-, RFP- and HCR-NTPase-RFP-controls are the same as those shown in table 1. The error bars indicate the standard deviations of at least 3 independently performed experiments.
