Biological fluid samples, such as plasma, serum, and urine, contain cell-free DNA (cfDNA). cfDNA is used in pathogen detection, and cfDNA targets are being used as biomarkers in oncology research. Isolation of cfDNA is challenging because of its low abundance in typical samples. In pathogen detection, virus particles are also typically in low abundance and therefore are challenging to capture. Thus, large volumes of biological fluids (which can be difficult to handle) are required to obtain sufficient amounts of cfDNA for analysis. We have developed scalable products capable of handling these large volumes while efficiently recovering cfDNA from a broad range of sample types in several format options.
