Also, unique anticoagulants is often employed 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 sorts (hemolysis) through blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Several miRNAs are identified to be expressed at higher levels in certain blood cell kinds, and these miRNAs are typically excluded from evaluation to avoid confusion.Moreover, it seems that miRNA concentration in serum is higher than in plasma, hindering direct comparison of studies using these different beginning supplies.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, and the TaqMan Low Density Array RT-PCR assay are amongst one of the most frequently applied high-throughput RT-PCR platforms for miRNA detection. Each makes use of a distinctive technique to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which results in different detection biases. ?Information analysis: One of the largest challenges to date is the normalization of circulating miRNA levels.
