On top of that, diverse anticoagulants might be used to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have different 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 in serum and plasma preparations. Numerous miRNAs are recognized to become expressed at high levels in specific blood cell kinds, and these miRNAs are ordinarily excluded from analysis to avoid confusion.Furthermore, it appears that miRNA concentration in serum is greater than in plasma, hindering direct comparison of studies applying these CEP-37440 site distinct beginning components.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 one of the most often employed high-throughput RT-PCR platforms for miRNA detection.
