The lysis of red blood cells or other cell types (hemolysis) through blood separation procedures can contaminate the miRNA content material in serum and plasma preparations. Many miRNAs are identified to become expressed at higher levels in precise blood cell types, and these miRNAs are commonly excluded from evaluation to avoid confusion.Moreover, it seems that miRNA concentration in serum is higher than in plasma, hindering direct comparison of studies employing these various beginning supplies.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 one of the most often utilised high-throughput RT-PCR platforms for miRNA detection. Every single makes use of a various approach to reverse transcribe mature miRNA molecules and to PCR-amplify the cDNA, which results in various detection biases. ?Data analysis: Certainly one of the most significant challenges to date is the normalization of circulating miRNA levels.
