cfDNA (ccfDNA) extraction for:

  • Liquid biopsy research
  • NIPT genomic research
  • Cancer genomic research
  • Transplant monitoring


  • Efficient Isolation of nucleic acids, with high input and low elution volumes
  • No carrier RNA
  • Low sample volume processing
  • Efficient recovery of small sized fragmented DNA
  • No organic extraction or ethanol precipitation

The cfKapture™ kit is a magnetic bead-based DNA extraction kit designed to isolate circulatingcell freeDNA (cfDNA) from human plasma and serum. The kit has a quick, simple, and automation friendly protocol that allows users to quickly extract high quality cfDNA that is ready for use in downstream applications such as qPCR, NGS, and bisulfite sequencing.
