Moreover, unique anticoagulants can be employed 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 varieties (hemolysis) for the duration of blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Several miRNAs are recognized to become expressed at high levels in distinct blood cell forms, and these miRNAs are ordinarily excluded from evaluation to avoid confusion.In addition, it seems that miRNA concentration in serum is greater than in plasma, hindering direct comparison of research using these various starting components.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 often utilised high-throughput RT-PCR platforms for miRNA detection.
