Furthermore, diverse anticoagulants can be utilised to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have different effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell varieties (hemolysis) through blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Quite a few miRNAs are known to be expressed at high levels in specific blood cell varieties, and these miRNAs are usually excluded from analysis to avoid confusion.Furthermore, it seems that miRNA concentration in serum is larger than in plasma, hindering direct comparison of studies making use of these distinct beginning materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, plus the TaqMan Low Density Array RT-PCR assay are amongst essentially the most frequently utilized high-throughput RT-PCR platforms for miRNA detection.
