“…Furthermore, 7.5% used immunoprecipitation [19,39], while 59% of the studies did not provide information about the separation process [12,15,18,20,21,23,[25][26][27]29,30,[32][33][34][35]38] (Figure 3, Supplementary Materials File S3). For RNA extraction, the studies used different commercially branded reagents s as Trizol (11%) [12,22,27] or kits such as as miRVANA (18.5%) [7,30,32,34,35] or miRNe (41%) [15,16,[19][20][21]23,24,31,36,38,39]. Twenty-two percent used other For RNA extraction, the studies used different commercially branded reagents such as Trizol (11%) [12,22,27] or kits such as as miRVANA (18.5%) [7,30,32,34,35] or miRNeasy (41%)…”
