On top of that, various anticoagulants may be utilised to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have distinctive effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell types (hemolysis) during blood separation procedures can contaminate the miRNA content in serum and plasma preparations. A number of miRNAs are identified to be expressed at higher levels in precise blood cell kinds, and these miRNAs are typically excluded from evaluation to prevent confusion.In addition, it seems that miRNA concentration in serum is larger than in plasma, hindering direct comparison of research employing these distinct 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 one of the most regularly applied high-throughput RT-PCR platforms for miRNA detection.
