Also, distinctive anticoagulants is often utilised to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have different effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell kinds (hemolysis) for the duration of blood separation procedures can contaminate the miRNA content in serum and plasma preparations. A number of miRNAs are recognized to be expressed at high levels in particular blood cell forms, and these miRNAs are ordinarily excluded from analysis to prevent confusion.Additionally, it appears that miRNA concentration in serum is larger than in plasma, hindering direct comparison of studies working with these different beginning materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, and also the TaqMan Low Density Array RT-PCR assay are among essentially the most frequently applied high-throughput RT-PCR platforms for miRNA detection.
