On top of that, various anticoagulants could be utilized 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 sorts (hemolysis) for the duration of blood separation procedures can contaminate the miRNA content material in serum and plasma preparations. Quite a few miRNAs are recognized to be expressed at higher levels in specific blood cell sorts, and these miRNAs are normally excluded from evaluation to prevent confusion.Additionally, it seems that miRNA concentration in serum is higher than in plasma, hindering direct comparison of research utilizing these distinctive beginning components.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, and the TaqMan Low Density Array RT-PCR assay are amongst one of the most regularly utilized high-throughput RT-PCR platforms for miRNA detection.
