Also, diverse anticoagulants might be made use of to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have distinctive effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell kinds (hemolysis) through blood separation procedures can contaminate the miRNA content in serum and plasma preparations. A number of miRNAs are known to be expressed at higher levels in distinct blood cell types, and these miRNAs are usually excluded from analysis to prevent confusion.Furthermore, it appears that miRNA concentration in serum is greater than in plasma, hindering direct comparison of research using these distinct beginning supplies.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, and the TaqMan Low Density Array RT-PCR assay are amongst by far the most regularly used high-throughput RT-PCR platforms for miRNA detection.
