On top of that, different anticoagulants may be 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 types (hemolysis) throughout blood separation procedures can contaminate the miRNA content in serum and plasma preparations. A number of miRNAs are known to become expressed at high levels in distinct blood cell sorts, and these miRNAs are usually excluded from analysis to avoid confusion.Furthermore, it appears that miRNA concentration in serum is greater than in plasma, hindering direct comparison of research utilizing these various 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 amongst by far the most often made use of high-throughput RT-PCR platforms for miRNA detection.
