Also, diverse anticoagulants may be employed 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 in serum and plasma preparations. Quite a few miRNAs are known to become expressed at higher levels in precise blood cell kinds, and these miRNAs are usually excluded from analysis to avoid confusion.In addition, it seems that miRNA concentration in serum is larger than in plasma, hindering direct comparison of research utilizing these various beginning materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, and also the TaqMan Low Density Array RT-PCR assay are amongst one of the most frequently employed high-throughput RT-PCR platforms for miRNA detection. Each makes use of a distinct tactic to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which benefits in distinct detection biases. ?Data analysis: One of the biggest challenges to date would be the normalization of circulating miRNA levels.
