Moreover, diverse anticoagulants may be used 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 in serum and plasma preparations. Several miRNAs are recognized to be expressed at high levels in distinct blood cell varieties, and these miRNAs are normally excluded from analysis to prevent confusion.In addition, it appears that miRNA concentration in serum is greater than in plasma, hindering direct comparison of research using these different starting materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, as well as the TaqMan Low Density Array RT-PCR assay are among the most frequently employed high-throughput RT-PCR platforms for miRNA detection.
