Analysis of complexes formed by oligonucleotides X and D with TRI by gel mobility shift assay in a buffer containing 50 mM Tris–acetate, 100 mM Na acetate, 10 mM Mg acetate at 24°C, at pH 5.0 (a) and 7.0 (b). The complex composition is indicated at the top. A 5′-³²P-labeled oligonucleotide is marked by an asterisk (*).
