AbraMag DNA Size Selection Magnetic Beads are designed to purify DNA fragments of desired size, 'tunable' by varying the beads-to-DNA ratio. DNA fragments are reversibly bound to paramagnetic particles while excess primers, salts, enzymes, and free nucleotides are washed away.

  • Meant to replace other SPRI magnetic beads at equivalent performance but better value (see Comparison Data).
  • Highly efficient removal of contaminants: primers, primer dimers, dNTPs, salts, etc.
  • For size cutoffs ranging from >50 to >800 bp (Size Selection)
  • Short processing times: no centrifugation or filtration
  • Tube or microplate format
  • Suitable for manual or automated process

Following the instructions included, the sample is added to the magnetic beads at a particular ratio. DNA fragments of the desired size bind to the beads in the presence of the optimized buffer. A magnet is used to secure the beads. Primers and/or other unwanted reagents are washed away in a series of two wash steps, and the DNA fragments are eluted and transferred to a new tube.

AbraMag Magnetic Beads are superparamagnetic, non-aggregating iron oxide particles (or ‘microspheres’) for capturing or purifying targets such as proteins, antigens, antibodies, DNA/RNA, cells, and more. AbraMag’s design enables faster binding kinetics, with high sensitivity & selectivity, in many biomedical and research applications—including automated HTS and manual applications.

Superior yield, purity, and quality over the leading competitors, all at a better value, because we design and manufacture them in-house.

  • Multiple Advantages – Over conventional methods (columns, centrifugation).
  • Superior Performance – We've designed them to match or outperform the competition.
  • Superior Capacity and Yield – High binding capacity for rapid and efficient target purification.
  • Superior Purity – Stable, pre-blocked particles provide clean purification even from complex samples.
  • Customizable – We can modify or create to suit your needs.
