In addition, various anticoagulants is usually used 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 varieties (hemolysis) during blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Numerous miRNAs are known to be expressed at high levels in certain blood cell types, and these miRNAs are commonly excluded from evaluation to avoid confusion.Moreover, it seems that miRNA concentration in serum is higher than in plasma, hindering direct comparison of studies making use of these diverse starting materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, and the TaqMan Low Density Array RT-PCR assay are among essentially the most regularly made use of high-throughput RT-PCR platforms for miRNA detection.
