Additionally, distinctive anticoagulants may be utilised 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 forms (hemolysis) through blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Many miRNAs are recognized to be expressed at high levels in distinct blood cell forms, and these miRNAs are usually excluded from analysis to avoid confusion.Additionally, it seems that miRNA concentration in serum is larger than in plasma, hindering direct comparison of research working with these distinct beginning components.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, and the TaqMan Low Density Array RT-PCR assay are amongst essentially the most regularly applied high-throughput RT-PCR platforms for miRNA detection.
