Also, various anticoagulants is usually utilized 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 forms (hemolysis) throughout blood separation procedures can contaminate the miRNA content in serum and plasma preparations. A number of miRNAs are identified to become expressed at higher levels in distinct blood cell forms, and these miRNAs are generally excluded from analysis to prevent confusion.Moreover, it seems that miRNA concentration in serum is greater than in plasma, hindering direct comparison of research working with these unique beginning materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, along with the TaqMan Low Density Array RT-PCR assay are among by far the most regularly applied high-throughput RT-PCR platforms for miRNA detection.
