MAGicBead™ cfDNA Isolation Kit

Not yet rated

The MAGicBead™ cfDNA Isolation Kit features a unique, magnetic bead surface chemistry that facilitates unparalleled cfDNA recovery from biofluids. Input volumes can range up to 10 mL of plasma. It is compatible with all open automation platforms and a wide range of sample types (serum, saliva, urine, etc.). This kit features a simple, streamlined extraction process with minimal number of steps and does not require the bead drying step common with other similar procedures. Eluted cfDNA is free of enzymatic inhibitors that can interfere with PCR or other sensitive downstream applications, including Next-Gen Sequencing.


Highlights for MAGicBeadTM cfDNA Isolation Kit (D4086):


  • Highest Yield: Robust cfDNA isolation from up to 10 mL plasma w/ unique MAGicBead™ surface technology 
  • NGS-Ready: High-quality cfDNA from plasma, saliva, urine, etc. is ideal for NGS


Compatible: With all open automation platforms

Elution Volume≥ 15 µl MAGicBead™ cfDNA Elution Buffer.
Fragment SizesFor plasma samples, DNA fragments will typically display a mono-nucleosomal peak in the 140-170 bp range and a genomic DNA fragments peak > 10 kb. However, other multi-nucleosomal apoptotic DNA fragments may also be present.
Processing Time1-1.5 hour (~15 minutes hands-on time).
PurityEluted cfDNA is NGS-ready. NOTE: Due to low levels of cfDNA available in cell-free biofluids, a spectrophotometer (e.g., NanoDrop) is not recommended for quantification or purity assessment.
Required EquipmentAn open automation platform: KingFisher Flex/Apex (Thermo-Fisher Scientific), Fluent® X (Tecan), Microlab® STAR™ (Hamilton), OT-2 (Opentrons) and others. For manual applications, a magnetic stand compatible with conical/centrifuge tubes/plates and a rotator capable of at least 30 rpm are needed.
Sample CompatibilityPlasma samples derived from most blood collection tube types are compatible, including Streck DNA BCT. Plasma samples derived from blood collection tubes with heparin are NOT compatible. Highly viscous biofluids, such as whole saliva and synovial fluids, may have limited compatibility. Refer to Appendix A (Page 6) for more details.
YieldTypical yields range from 0.5 ng to 20 ng from healthy donor plasma samples. This can range from 0.1 ng to 100 ng depending on the health status of donors.
