Furthermore, various anticoagulants might be made use of to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have distinctive effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell kinds (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 specific blood cell types, and these miRNAs are generally excluded from evaluation to prevent confusion.Moreover, it appears that miRNA concentration in serum is higher 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 one of the most regularly used high-throughput RT-PCR platforms for miRNA detection.
