Moreover, distinct anticoagulants can 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 forms (hemolysis) during blood separation procedures can contaminate the miRNA content material in serum and plasma preparations. Quite a few miRNAs are known to be expressed at higher levels in precise blood cell types, and these miRNAs are ordinarily excluded from analysis to prevent confusion.Furthermore, it seems that miRNA concentration in serum is greater than in plasma, hindering direct comparison of studies using these distinctive starting materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, plus the TaqMan Low Density Array RT-PCR assay are among probably the most frequently used high-throughput RT-PCR platforms for miRNA detection.
