On top of that, distinct anticoagulants can be utilized 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 kinds (hemolysis) in the course of blood separation procedures can contaminate the miRNA content material in serum and plasma preparations. Several miRNAs are known to be expressed at high levels in precise blood cell forms, and these miRNAs are normally excluded from analysis to avoid confusion.Moreover, it seems that miRNA concentration in serum is larger than in plasma, hindering direct comparison of research using these different starting components.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 frequently employed high-throughput RT-PCR platforms for miRNA detection. Every single makes use of a various strategy to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which results in distinctive detection biases. ?Data evaluation: Certainly one of the greatest challenges to date is the normalization of circulating miRNA levels.
