In addition, various anticoagulants is often made use of to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have different effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell sorts (hemolysis) during blood separation procedures can contaminate the miRNA content material in serum and plasma preparations. Several miRNAs are recognized to become expressed at high levels in distinct blood cell varieties, and these miRNAs are ordinarily excluded from evaluation to avoid confusion.In addition, it seems that miRNA concentration in serum is higher than in plasma, hindering direct comparison of research using these distinct beginning components.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, plus the TaqMan Low Density Array RT-PCR assay are among essentially the most often used high-throughput RT-PCR platforms for miRNA detection. Each makes use of a unique technique to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which outcomes in different detection biases. ?Information evaluation: Among the largest challenges to date could be the normalization of circulating miRNA levels.
