In addition, different anticoagulants might be used to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have unique effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell kinds (hemolysis) throughout blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Numerous miRNAs are known to be expressed at high levels in certain blood cell kinds, and these miRNAs are usually excluded from evaluation to prevent confusion.Moreover, it seems that miRNA concentration in serum is larger than in plasma, hindering direct comparison of studies applying these various beginning components.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 the most frequently employed high-throughput RT-PCR platforms for miRNA detection.
