Figure 1. Western blot of crosslinked extracts probed with Anti‐Rct1 antibody. Lane 1: control sample (before crosslinking); lane 2: sample crosslinked with formaldehyde.

Figure 2. Electrophoresis of PCR reactions from CLIP samples (see Section 26.2.14) processed with different concentrations of RNase T1. Lane 1: marker GeneRuler (Fermentas), lane 2: untreated by RNAse, lane 3: positive control for PCR reaction, lane 4: treated with low concentration (dilution 1 : 5000), lane 5: treated with high concentrations (dilution 1 : 100) of RNase T1.
