NVIGEN designs and engineers our nanoparticles (nanobeads) and surface conjugations. Our ready-to-use nanoparticle reagents are compatible and ideal for experimental workflows, molecular imaging, IVD and therapeutics. We also offer services that can customize nanoparticles with specific surface functional groups to bind specific ligands.

Our most popular products for DNA size selection, DNA capture, Cell free DNA Extraction, and protein co-immunoprecipitation come from our MagVigen™ platform. MagVigen™ nanoparticles have strong magnetism, sensitivity and binding specificity. We are able to customize and fine-tune surface conjugation and particle functionalities, making MagVigen™ ideal for use in a wide variety or applications. Magnetic separation is fast yet gentle, causing minimal disruption to your target proteins, permitting the isolation and preservation of labile compositions and conformations that might otherwise being interfered. See below for more in-depth descriptions of our magnetic beads and how they can assist you in your research.


MagVigen magnetic nanoparticles for sequencing and biopsy

Magnetic nanoparticles with high magnetic response and binding specificity.

MagVigen™ magnetic nanoparticles easily respond to an external magnet. MagVigen™ is one of our top selling magnetic bead products a which has maximum versatility in its usages.

Advantages of MagVigen™ magnetic nanoparticles:

  • Magnetic separation is simple and fast. No columns or centrifugation needed.
  • No residual magnetism when magnetic field is removed.
  • Nano-size beads minimize interference within interacting complexes.
  • High recovery rate and performance consistency.
  • High capacity and elution efficiency.
  • Enable novel biomarker identification.
  • Economical.

Applications of MagVigen™ magnetic nanoparticles:

  • Protein-antibody purification
  • Immunoprecipitation
  • Chromatin immunoprecipitation
  • DNA and RNA purification
  • Cell separation and enrichment
  • Molecular enrichment

Three easy steps using MagVigen™ - protein A nanoparticles for protein enrichment and purification:

MagVigen protein enrichment and purification workflow

  1. Mix: Mix MagVigen™ nanoparticles with DNA/RNA sample.
  2. Bind: When mixed with a sample, MagVigen™ nanoparticles bind to the desired target (i.e. cells, pathogenic microorganisms, nucleic acids, peptides, proteins or protein complexes, etc). This interaction relies on the specific affinity of the ligand conjugated to the surface of the nanoparticles. NVIGEN engineers the surface conjugations you desire.
  3. Wash: The beads respond to a magnetic force (by use of a magnet), allowing bound material to be rapidly and efficiently separated from the rest of the sample. After unbound materials are removed by aspiration, the nanoparticle-bound targets are washed by using the magnet.
  4. Elute: The bound target is released from the nanoparticles and can be used for downstream applications.
