In addition, different anticoagulants might be used to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have various effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell varieties (hemolysis) during blood separation procedures can contaminate the miRNA content material in serum and plasma preparations. A number of miRNAs are known to become expressed at higher levels in certain blood cell varieties, and these miRNAs are commonly excluded from evaluation to avoid confusion.In addition, it appears that miRNA concentration in serum is higher than in plasma, hindering direct comparison of studies utilizing these distinct beginning materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, and the TaqMan Low Density Array RT-PCR assay are among essentially the most often made use of high-throughput RT-PCR platforms for miRNA detection. Each utilizes a distinctive technique to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which outcomes in different detection biases. ?Information evaluation: Among the most significant challenges to date is definitely the normalization of circulating miRNA levels.
