On top of that, distinctive anticoagulants may be made use of to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have distinctive effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell kinds (hemolysis) in the course of blood separation procedures can contaminate the miRNA content material in serum and plasma preparations. Several miRNAs are identified to become expressed at high levels in certain blood cell varieties, and these miRNAs are typically excluded from evaluation to avoid confusion.In addition, it seems that miRNA concentration in serum is higher than in plasma, hindering direct comparison of research using these distinctive starting materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, along with the TaqMan Low Density Array RT-PCR assay are among essentially the most often utilized high-throughput RT-PCR platforms for miRNA detection.
