In addition, distinctive anticoagulants is often 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 material in serum and plasma preparations. Several miRNAs are identified to become expressed at high levels in precise blood cell types, and these miRNAs are typically excluded from analysis to avoid confusion.Additionally, it appears that miRNA concentration in serum is larger than in plasma, hindering direct comparison of research making use of these unique starting 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 one of the most frequently used high-throughput RT-PCR platforms for miRNA detection.
