The ability to profile and quantify small non-coding RNAs (sRNAs), specifically microRNAs (miRNAs), using highthroughput sequencing is challenging because of their small size. We developed QsRNA-seq, a method for preparation of sRNA libraries for high-throughput sequencing that overcomes this difficulty by enabling a gelfree separation of fragments shorter than 100 nt that differ only by 20 nt in length. |
