Bead Xtract cfDNA Extraction Kit – Magnetic Bead-Based DNA Isolation for Liquid Biopsy & NGS

Bead Xtract
High-Efficiency Magnetic Bead cfDNA Extraction for Research and Clinical Use


Bead Xtract enables high-yield cfDNA extraction from plasma or serum using magnetic bead technology. Ideal for manual or automated workflows in liquid biopsy, qPCR, ddPCR, and NGS applications.

Unlock Superior cfDNA Recovery with Bead Xtract

The Bead Xtract revolutionizes cell-free DNA isolation with unmatched efficiency and scalability. Designed for both manual and automated workflows, this magnetic bead-based kit ensures rapid, high-purity cfDNA recovery from up to 10 mL of plasma or serum, ideal for cancer research, liquid biopsies, and non-invasive diagnostics. Since no funnels or vacuum filtration are required, manual handling time can be minimized.

Minimized Contamination, Enhanced Purity

  • Optimized dissolution and binding buffers maximize small DNA fragment recovery
  • Reduces gDNA contamination, ensuring high-quality cfDNA suitable for qPCR, ddPCR, and NGS
Figure 1 Average DNA yield (ng) extracted from 1 ml plasma replicates using a range of different bead-based and spin-column based extraction kits. cfDNA was extracted following the manufacturer’s instructions and eluted into 50 µl of elution buffer. DNA concentration was determined using high sensitivity reagents on the Qubit 3.0 (Invitrogen).

High Performance cfDNA Extraction

  • Magnetic bead technology enables superior DNA binding capacity, resulting in higher cfDNA yield from plasma samples
  • Optimized for efficient elution volumes (final elution volume of only 30–60 µL), even when processing 10 mL plasma samples
  • Eliminates vacuum filtration, streamlining the workflow for NGS-ready cfDNA
