Simple and cost-effective laboratory methods to evaluate and validate cell-free DNA isolation

摘要

ObjectiveIn the present study, we investigated different simple and cost effective methods to evaluate and validate cell free DNA (cfDNA) isolation. The ability of the QIAamp DNA Blood Mini Kit method to extract cfDNA was assessed by several approaches, including purification of endogenous cfDNA and exogenous spike-in control material, prior to plasma extraction, and followed by quantitative-PCR.
