Purification of recombinant miRNA molecules. (A) Representative FPLC-UV trace during the purification of the model BioRNAGly/miR-7-5p with a highlighted peak for target fraction collection. (B) Urea–PAGE analysis of BioRNAGly/miR-7-5p fractions. (C) HPLC determination of the purity (99.6%) of final BioRNAGly/miR-7-5p product. (D, E) Urea–PAGE analyses depicting FPLC-purified BioRNAGly/miRNAs and BioRNALeu/miRNAs, respectively (50 ng RNA/lane). Purification of BioRNALeu/miR-7-5p, -126b-3p, -133a-3p, and -200b-3p has been published recently (Li et al. 2021).
