Additionally, different anticoagulants can be used 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 sorts (hemolysis) through blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Various miRNAs are recognized to become expressed at high levels in specific blood cell forms, and these miRNAs are normally excluded from evaluation to prevent confusion.Furthermore, it seems that miRNA CUDC-907 site concentration in serum is larger than in plasma, hindering direct comparison of studies applying these distinctive starting supplies.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, plus the TaqMan Low Density Array RT-PCR assay are among by far the most often used high-throughput RT-PCR platforms for miRNA detection.
