Discovery and characterization of microRNAs (miRNAs) and other families of small RNAs lead researchers to study their structures/functions and their expression patterns. The splinted ligation method described here is based on nucleic acid hybridization. It is optimized for the direct labeling and quantitative detection of small RNAs. A specific bridge DNA oligonucleotide is used, which is perfectly complementary to both the target small RNA and a labeled ligation nucleic acid. The target RNA is subsequently labeled by ligation, detected by analysis in denaturing conditions, and quantified by phosphorimaging. The protocol doesn’t require any specific material, and the procedure is fast and sensitive.
