Fig 2 — Separation of two species (Peak 1 and Peak 2 in panel A) was achieved using ion pairing RP-HPLC. (B) RNA integrity analysis of the isolated Peak 1 and Peak 2 materials demonstrates that Peak 1 consists of fragmented species (red trace), and Peak 2 is predominantly intact mRNA (blue trace). The unfractionated starting material electropherogram is shown in the black trace.
