Integrity of extracted RNAs. (a) Total RNA (left) and small RNAs (right) were loaded on 15% denaturing PAGE gels and stained with 0.5 μg/ml EtBr in buffer. (b) Total RNA (left) and small RNAs (right) were loaded on 1.2% agarose gels and stained with 0.5 μg/ml EtBr in buffer. (c) Northern blot of miRNA5078 with variable amounts of total RNA (left) and small RNAs (right). The exposure times are indicated.
