CUDC-907 web Furthermore, distinct anticoagulants is often applied to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have distinct effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell sorts (hemolysis) during blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Many miRNAs are identified to be expressed at higher levels in precise blood cell varieties, and these miRNAs are typically excluded from analysis to prevent confusion.Furthermore, it seems that miRNA concentration in serum is greater than in plasma, hindering direct comparison of research making use of these distinctive beginning components.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, plus the TaqMan Low Density Array RT-PCR assay are amongst the most often applied high-throughput RT-PCR platforms for miRNA detection.
