Abstract
MicroRNA capture affinity technology (miR-CATCH) uses affinity capture biotinylated antisense oligonucleotides to co-purify a target transcript together with all its endogenously bound miRNAs. The miR-CATCH assay is performed to investigate miRNAs bound to a specific mRNA. This method allows to have a total vision of miRNAs bound not only to the 3′UTR but also to the 5′UTR and Coding Region of target messenger RNAs (mRNAs).
