On top of that, diverse anticoagulants can be made use of to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have diverse effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell forms (hemolysis) during blood separation procedures can contaminate the miRNA content material in serum and plasma preparations. Various miRNAs are recognized to be expressed at higher levels in particular blood cell varieties, and these miRNAs are commonly excluded from analysis to prevent confusion.Furthermore, it seems that miRNA concentration in serum is higher than in plasma, hindering direct comparison of research working with these diverse 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 probably the most often utilized high-throughput RT-PCR platforms for miRNA detection.
