Also, distinct anticoagulants can be utilized 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 types (hemolysis) throughout blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Numerous miRNAs are known to be expressed at higher levels in precise blood cell kinds, and these miRNAs are generally excluded from evaluation to avoid confusion.In addition, it appears that miRNA concentration in serum is larger than in plasma, hindering direct comparison of studies employing 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 one of the most often utilised high-throughput RT-PCR platforms for miRNA detection.
