On top of that, distinctive anticoagulants can be utilised to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have various 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. Quite a few miRNAs are known to be expressed at high levels in distinct blood cell sorts, and these miRNAs are commonly excluded from evaluation to prevent confusion.Furthermore, it appears that miRNA concentration in serum is greater than in plasma, hindering direct comparison of studies employing these various beginning components.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, along with the TaqMan Low Density Array RT-PCR assay are amongst the most often utilized high-throughput RT-PCR platforms for miRNA detection.
