Also, unique anticoagulants could be applied 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 types (hemolysis) through blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Many miRNAs are recognized to become expressed at higher levels in specific blood cell kinds, and these miRNAs are normally excluded from analysis to avoid confusion.Furthermore, it seems that miRNA concentration in serum is greater than in plasma, hindering direct comparison of research employing these different starting materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, plus the TaqMan Low Density Array RT-PCR assay are amongst essentially the most regularly utilised high-throughput RT-PCR platforms for miRNA detection.

Spiking samples with RNA controls and/or normalization of miRNA levels to volume are a few of the tactics utilised to standardize analysis.
