In addition, distinct anticoagulants is often applied to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have various effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell kinds (hemolysis) through blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Numerous miRNAs are recognized to be expressed at high levels in precise blood cell forms, and these miRNAs are ordinarily excluded from evaluation to prevent confusion.Additionally, it seems that miRNA concentration in serum is higher than in plasma, hindering direct comparison of research working with these different beginning components.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, along with the TaqMan Low Density Array RT-PCR assay are among by far the most often employed high-throughput RT-PCR platforms for miRNA detection.
