Figure 3From: Systematic comparison of RNA extraction techniques from frozen and fresh lung tissues: checkpoint towards gene expression studiesTotal yield and purity performance of RNA isolated from frozen and fresh lung tissues with SGC- and GTC-based techniques. (A) Yield of total RNA in nanogram (ng), which was significantly higher in frozen and fresh lung tissue with GTC- than SGC-based isolation, respectively. (B) Total RNA purity assessment on the basis of A260/A280.Back to article page
