Magnetic Beads

Obtaining high quality nucleic acids is critical for downstream molecular biology applications such as qPCR, qRT-PCR and NGS. Our magnetic beads are ideally suited for this purpose and are offered as either PureSil for general extractions or SeqPure for PCR cleanup and size selection.
BioChain's PureSil beads are silica coated and have been used for over 3 million Covid-19 tests throughout the United States. They were also the tool for a landmark early cancer detection study from Bert Vogelstein’s laboratory in Johns Hopkins University. Our magnetic beads have user-friendly protocols and can easily be applied to automation. Bulk quantities and OEM manufacturing are also available for purchase at highly competitive prices.


  • Magnetic beads facilitate nucleic acid extraction
  • Can be used in automated protocols


  • Nucleic acid extraction
  • PCR clean-up

Quality Control

  • The quality and purity of DNA fragments after using SeqPure PCR purification kit were tested by a spectrophotometer and electrophoresis. A260/280 is between 1.8 and 2.0 and A260/230 is >2.0. The DNA is also visualized on an agarose gel to confirm recovery of fragments 100bp or above
  • PureSil beads are tested by extracting cfDNA from human control plasma. The resulting eluted cfDNA is tested for yield and purity and compared to known yields and purity of the same control human plasma sample to ensure efficacy and consistency.
