On top of that, unique anticoagulants could be used 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 varieties (hemolysis) during blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Numerous miRNAs are recognized to be expressed at high levels in specific blood cell sorts, and these miRNAs are usually excluded from evaluation to prevent confusion.Moreover, it seems that miRNA concentration in serum is higher than in plasma, hindering direct comparison of research using these diverse starting materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, and the TaqMan Low Density Array RT-PCR assay are among essentially the most regularly utilized high-throughput RT-PCR platforms for miRNA detection. Every single utilizes a diverse approach to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which results in distinct detection biases. ?Information evaluation: Among the biggest challenges to date is the normalization of circulating miRNA levels.
