Also, different anticoagulants may be employed 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 varieties (hemolysis) during blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Various miRNAs are known to be expressed at high levels in specific blood cell sorts, and these miRNAs are ordinarily excluded from evaluation to prevent confusion.Additionally, it seems that miRNA concentration in serum is greater than in plasma, hindering direct comparison of research utilizing these diverse beginning components.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, plus the TaqMan Low Density Array RT-PCR assay are amongst one of the most frequently utilised high-throughput RT-PCR platforms for miRNA detection.
