Moreover, distinct anticoagulants is usually utilized 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 forms (hemolysis) in the course of blood separation procedures can contaminate the miRNA content material in serum and plasma preparations. Many miRNAs are recognized to be expressed at higher levels in precise blood cell sorts, and these miRNAs are typically excluded from evaluation to avoid confusion.Additionally, it appears that miRNA concentration in serum is higher than in plasma, hindering direct comparison of studies utilizing these diverse beginning supplies.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, and the TaqMan Low Density Array RT-PCR assay are among one of the most often utilized high-throughput RT-PCR platforms for miRNA detection.
