Figure 7From: Intronic RNAs constitute the major fraction of the non-coding RNA in mammalian cellsDetection of long transcripts in intronic regions using RT-PCR. Reactions were done with (“+”) and without (“-”) reverse transcriptase. The size range where the expected PCR products should fall is shown on the right. M- size standard.
