Figure 2From: Time course analysis of RNA stability in human placentaAnalysis of total RNA integrity according to delay time of storage and to handling conditions. The integrity of total RNA in placental tissues stored at + 4°C for 0 to 96 H, was determined by Agilent Bioanalyzer assay. Results (mean +/- SEM, each experiment in duplicate) were expressed as RIN values (top of the figure), or 28S:18S ratios (bottom of the figure). RNA was prepared from placental samples transferred directly to RNA later™(protocol A), or dissected before banking (protocol B). p values were determined by ANOVA. p < 0.05 was considered to be significant. RIN protocol A versus Protocol B: p = 0.007.Back to article page
