Background

Small RNAs are noncoding RNAs shorter than 100 nucleotides. One of the most commonly studied small RNA families are microRNAs (miRNA) that can bind to target mRNAs and inhibit their translation or induce degradation. A functional study of miRNAs and exploration of their utility as disease markers require miRNA extraction from biological samples, which contain large amounts of interfering compounds for downstream RNA identification and quantification. The most common extraction methods employ silica columns or the TRIzol reagent but these result in low levels of small RNA recovery.

*Abstract

Prof. Wenwan Zhong and her lab at UCR have developed a method to recover small RNAs using TiO₂ fibers which results in a 200-fold improvement in yield when compared to commercially available SiO₂ columns.
