Moreover, distinctive anticoagulants may be utilized 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 sorts (hemolysis) for the duration of blood separation procedures can contaminate the miRNA content material in serum and plasma preparations. Various miRNAs are identified to become expressed at high levels in certain blood cell types, and these miRNAs are normally excluded from analysis to prevent confusion.Additionally, it seems that miRNA concentration in serum is larger than in plasma, hindering direct comparison of studies making use of these various starting supplies.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, along with the TaqMan Low Density Array RT-PCR assay are among one of the most regularly made use of high-throughput RT-PCR platforms for miRNA detection.
