Moreover, distinct anticoagulants may be utilised 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 kinds (hemolysis) throughout blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Quite a few miRNAs are recognized to become expressed at high levels in particular blood cell forms, and these miRNAs are usually excluded from analysis to avoid confusion.In addition, it appears that miRNA concentration in serum is Etomoxir web higher than in plasma, hindering direct comparison of studies employing these diverse beginning supplies.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, plus the TaqMan Low Density Array RT-PCR assay are amongst by far the most frequently used high-throughput RT-PCR platforms for miRNA detection.
