Also, unique anticoagulants can be made use of to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have distinct 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. Numerous miRNAs are recognized to become expressed at higher levels in particular blood cell kinds, and these miRNAs are generally excluded from evaluation to prevent confusion.Moreover, it seems that miRNA concentration in serum is larger than in plasma, hindering direct comparison of studies employing these diverse starting components.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, and the TaqMan Low Density Array RT-PCR assay are among the most frequently made use of high-throughput RT-PCR platforms for miRNA detection. Each and every makes use of a distinct approach to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which final results in different detection biases. ?Data analysis: Among the greatest challenges to date could be the normalization of circulating miRNA levels.
