Additionally, various anticoagulants can be utilized to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have diverse 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. A number of miRNAs are identified to be expressed at higher levels in particular blood cell forms, and these miRNAs are ordinarily excluded from analysis to prevent confusion.Furthermore, it seems that miRNA concentration in serum is larger than in plasma, hindering direct comparison of research working with these distinctive beginning 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 often applied high-throughput RT-PCR platforms for miRNA detection.
