Also, various anticoagulants can 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 kinds (hemolysis) for the duration of blood separation procedures can contaminate the miRNA content material in serum and plasma preparations. Quite a few miRNAs are identified to be expressed at higher levels in certain blood cell varieties, and these miRNAs are generally excluded from analysis to avoid confusion.Furthermore, it seems that miRNA concentration in serum is higher than in plasma, hindering direct comparison of studies making use of these diverse beginning supplies.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, plus the TaqMan Low Density Array GDC-0810 RT-PCR assay are among the most regularly employed high-throughput RT-PCR platforms for miRNA detection.
