(D) Images of beads binding to EmGFP-Tm1-I (green) and DIG labelled in vitro transcribed RNA fragments (magenta).(E, F) Mean DIG-Cy5 fluorescence measured on beads capturing the RNA fragment, with or without UV cross-linking, indicated below the charts. P values of pairwise Mann-Whitney U tests are indicated. In panel F, none of the non-cross-linked samples differ significantly from the no RNA control (p>0.05). Numbers below the plots indicate the number of beads analysed.
