Additionally, distinct anticoagulants is often employed 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 sorts (hemolysis) during blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Many miRNAs are known to become expressed at high levels in certain blood cell forms, and these miRNAs are normally excluded from evaluation to prevent confusion.Additionally, it seems that miRNA concentration in serum is higher than in plasma, hindering direct comparison of research utilizing these different beginning materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, as well as the TaqMan Low Density Array RT-PCR assay are amongst the most regularly used high-throughput RT-PCR platforms for miRNA detection. Each and every utilizes a different strategy to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which final results in different detection biases. ?Data analysis: One of the most significant challenges to date is definitely the normalization of circulating miRNA levels.

Spiking samples with RNA controls and/or normalization of miRNA levels to volume are a few of the techniques made use of to standardize evaluation. Also, several studies apply diverse statistical strategies and criteria for normalization, background or control reference s.
