Furthermore, distinctive anticoagulants could be used to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have different effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell sorts (hemolysis) in the course of blood separation procedures can contaminate the miRNA content material in serum and plasma preparations. Many miRNAs are recognized to become expressed at higher levels in certain blood cell varieties, and these miRNAs are normally excluded from analysis to prevent confusion.Moreover, it appears that miRNA concentration in serum is larger than in plasma, hindering direct comparison of studies working with these various beginning components.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, along with the TaqMan Low Density Array RT-PCR assay are amongst essentially the most regularly applied high-throughput RT-PCR platforms for miRNA detection. Each makes use of a different strategy to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which results in various detection biases. ?Information evaluation: One of the biggest challenges to date will be the normalization of circulating miRNA levels.
