The purification of cell-free DNA (cfDNA) is challenging because of the low concentrations, its instability and the small fragment sizes. Nevertheless the information it delivers is highly valuable for cancer studies and research of prenatal testing using technologies as NGS and ddPCR. The chemagic™ cfDNA kits enable the automated and efficient extraction of cfDNA from 0.5 - 5 ml plasma in 24-well or 96-well format in maximal 2 hours with minimal hands-on time. The chemagic cfDNA kits show equivalent yields as well as purities compared to the manual silica based gold standard kit.

Features of the chemagic cfDNA Purification Workflows

chemagen developed the chemagic cfDNA kits to isolate cfDNA from 0.2 - 18 ml fresh and frozen plasma derived from EDTA, citrate or other blood collection tubes within 90 - 120 minutes with the chemagic 360 instrument . The chemagic cfDNA kits are based on chemagen technology using M-PVA Magnetic Beads for the isolation of cfDNA. The cfDNA binds to paramagnetic beads, which are magnetically separated from the sample material. During subsequent steps, contaminants are removed and the purified cfDNA is transferred into an elution medium. The automated sample processing by the chemagic 360 instrument excludes cross-contamination and ensures safe handling of infectious sample material.
