Additionally, 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 material in serum and plasma preparations. A number of miRNAs are known to be expressed at high levels in certain blood cell types, and these miRNAs are generally excluded from evaluation to avoid confusion.Moreover, it appears that miRNA concentration in serum is higher than in plasma, hindering direct comparison of studies utilizing these diverse starting materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, plus the TaqMan Low Density Array RT-PCR assay are amongst essentially the most often made use of high-throughput RT-PCR platforms for miRNA detection.
