Moreover, distinctive anticoagulants could be employed to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have diverse effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell sorts (hemolysis) for the duration of blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Many miRNAs are identified to be expressed at higher levels in certain blood cell kinds, and these miRNAs are ordinarily excluded from analysis to avoid confusion.Moreover, it appears that miRNA concentration in serum is larger than in plasma, hindering direct comparison of research applying these distinct beginning 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 regularly employed high-throughput RT-PCR platforms for miRNA detection. Every single utilizes a various tactic to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which results in distinct detection biases. ?Information analysis: One of the largest challenges to date is definitely the normalization of circulating miRNA levels.
