Also, different anticoagulants is usually applied to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have distinctive effects on plasma composition and downstream molecular assays. 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 known to become expressed at high levels in certain blood cell sorts, and these miRNAs are normally excluded from evaluation to prevent confusion.In addition, it appears that miRNA concentration in serum is larger than in plasma, hindering direct comparison of research working with these different beginning supplies.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, plus the TaqMan Low Density Array RT-PCR assay are among essentially the most often utilised high-throughput RT-PCR platforms for miRNA detection.
