Also, diverse anticoagulants may be used to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have different 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 material in serum and plasma preparations. Several miRNAs are known to be expressed at higher levels in precise blood cell kinds, and these miRNAs are typically excluded from analysis to prevent confusion.Furthermore, it appears that miRNA concentration in serum is greater than in plasma, hindering direct comparison of research utilizing these distinctive starting materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, and the TaqMan Low Density Array RT-PCR assay are among essentially the most frequently used high-throughput RT-PCR platforms for miRNA detection.
