Also, distinctive anticoagulants could be applied to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have unique effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell types (hemolysis) during blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Quite a few miRNAs are recognized to become expressed at higher levels in particular blood cell forms, and these miRNAs are ordinarily excluded from analysis to prevent confusion.Moreover, it appears that miRNA concentration in serum is greater than in plasma, hindering direct comparison of research using these distinctive beginning materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, as well as the TaqMan Low Density Array RT-PCR assay are amongst the most regularly used high-throughput RT-PCR platforms for miRNA detection. Every single makes use of a distinct tactic to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which results in different detection biases. ?Data analysis: Among the biggest challenges to date would be the normalization of circulating miRNA levels.
