Furthermore, unique anticoagulants can be applied 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) in the course of blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Several miRNAs are recognized to become expressed at higher levels in precise blood cell kinds, and these miRNAs are commonly Sinensetin web excluded from analysis to prevent confusion.Furthermore, it appears that miRNA concentration in serum is greater than in plasma, hindering direct comparison of studies employing these distinct starting supplies.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, plus the TaqMan Low Density Array RT-PCR assay are among essentially the most frequently employed high-throughput RT-PCR platforms for miRNA detection.
