In addition, distinct anticoagulants could be employed to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have distinct effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell forms (hemolysis) during blood separation procedures can contaminate the miRNA MedChemExpress Compound C dihydrochloride content in serum and plasma preparations. Various miRNAs are known to be expressed at high levels in particular blood cell varieties, and these miRNAs are usually excluded from evaluation to avoid confusion.Additionally, it seems that miRNA concentration in serum is higher than in plasma, hindering direct comparison of studies working with these various starting 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 among essentially the most regularly made use of high-throughput RT-PCR platforms for miRNA detection.
