Magnetic Circulating Free DNA Extraction Kit

EmerTher Magnetic Circulating Free DNA Extraction Kit is used for extracting circulating free DNA (cfDNA) from acellular tissue fluid such as plasma with high efficiency and is an ideal sample preparation kit for Noninvasive Prenatal Testing (NIPT) or liquid biopsy.

Product Features
  • High throughput: Fast extraction, completed in about 1 hr

  • Process 200 µl -3 ml plasma/prep. Sample volume is scalable

  • cfDNA peaks reside at ~170-200 bp with high purity and high concentrations

  • Automation: Compatible with a variety of automatic magnetic bead processors

Extraction Procedures

Manual Extraction

Magnetic beads


Proteins and other cellular debris

1. Add sample to a lysis-extraction solution to enable cell lysis, DNA release and DNA binding to magnetic beads in one step

2. Apply magnetic force enabling easy wash of the beads with Washing Solution I & II

3. Elution of DNA from the beads using water or TE buffer

Automated Extraction

Pre-packed plates for easy automation; compatible with a variety of automatic magnetic bead processors and liquid handling systems
