Moreover, different anticoagulants may be used 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 kinds (hemolysis) for the duration of blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Several miRNAs are known to be expressed at high levels in precise blood cell kinds, and these miRNAs are generally excluded from analysis to avoid confusion.Furthermore, it appears that miRNA concentration in serum is GrazoprevirMedChemExpress MK-5172 Larger than in plasma, hindering direct comparison of research applying these unique 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 probably the most often employed high-throughput RT-PCR platforms for miRNA detection.
