In addition, various 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) throughout blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Quite a few miRNAs are recognized to be expressed at high levels in precise blood cell types, and these miRNAs are normally excluded from evaluation to avoid confusion.Moreover, it seems that miRNA GMX1778 concentration in serum is larger than in plasma, hindering direct comparison of research using these unique beginning components.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, and also the TaqMan Low Density Array RT-PCR assay are amongst essentially the most regularly made use of high-throughput RT-PCR platforms for miRNA detection. Every single makes use of a various tactic to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which outcomes in different detection biases. ?Data evaluation: One of the biggest challenges to date is definitely the normalization of circulating miRNA levels.
