Figure 1From: Changes in cellular microRNA expression induced by porcine circovirus type 2-encoded proteins Size distribution of small RNA sequences. The clean reads ranging from 18-nt to 36-nt in size were selected from each small RNA cDNA library after deep sequencing, as described in Materials and Methods. The majority of them were 22Â nt, which is consistent with the typical size of miRNAs.Back to article page
