Fig. 2From: Selective gene expression analysis of the neuroepithelial body microenvironment in postnatal lungs with special interest for potential stem cell characteristicsElectropherograms demonstrating the 18S and 28S rRNA peaks, corresponding to the level of intact RNA in each sample, are used for total RNA quality analysis of random LMD-collected and pooled small samples from cryostat sections of brain (PD21; a), embryonic (ED14; b) and postnatal lung (PD21, c). In the brain (RNA Quality Indicator, RIN = 7.9) and embryonic mouse lung (RIN = 8.9), high quality intact RNA can be detected, while in the identically processed postnatal mouse lung tissue a large part of the RNA appears to be degraded (RIN = 3.2)Back to article page
