M-PVA Magnetic Beads

Einleitungstext

Magnetic Beads Based on Polyvinyl Alcohol

chemagen started its business with the development, functionalization, and production of magnetic particles based on polyvinyl alcohol, referred to as M-PVA Magnetic Beads. These beads represent a new class of particles and allow applications in nearly every scientific field requiring the isolation of specific biomolecules.

Develop your own assay with our M-PVA Magnetic Beads. Contact our OEM team for further support.

Interested in receiving M-PVA Magnetic Beads?

In case you are interested to test the M-PVA Magnetic Beads for your application, check the table of magnetic beads below and fill out the contact form with your details.


The picture shows a schematic representation of the M-PVA Magnetic Bead structure. Particles of magnetite are embedded in the polyvinyl alcohol matrix conferring paramagnetic properties to the beads.

The surface of the M-PVA Magnetic Beads can be functionalized with many different groups and modified with individually tuneable loadings. The figure on the left shows a selection of functionalized, activated beads offered by chemagen as standard and ready-to-use reagents.

Applications of M-PVA Magnetic Beads

Thanks to their hydrophilic surface, M-PVA Magnetic Beads show a very little affinity for most biological molecules, opposite to the majority of commercially available beads that are based on hydrophobic materials such as polystyrene. This feature makes activated M-PVA Magnetic Beads ideal for the separation of specific molecules from complex mixtures.

Standard functionalized M-PVA Magnetic Beads:

  • Carboxylated beads
  • Oligo(dT)
  • Streptavidin (SAV)
  • N-hydroxysuccinimidyl (NHS) ester
  • Primary amine functionalized
  • Epoxide functionalized
  • OH-functionalized beads

Major applications:

  • Isolation of nucleic acids
  • Detection or isolation of specific sequences or species of nucleic acids
  • Preparation of molecule libraries (e.g. oligonucleotides, DNA, RNA, proteins, or smaller molecules) using combinatorial strategies
  • Screening and selection of DNA libraries
  • Binding of biotinylated proteins
  • Affinity purification of proteins (e.g. antibodies or lectins)
M-PVA Magnetic Beads

Outstanding properties

  • High magnetite content for fast magnetic separation, even from large sample volumes
  • Polydisperse particles for a uniform reproducibility of magnetic separation
  • µm sized beads present a high active surface per volume and allow efficient adaptation to specific applications
  • Mechanical robustness allows different kinds of processing and facilitates automated use
  • Chemical functionalization of the matrix with different modifications for high and specific binding capacity
  • Hydrophilicity of the PVA surface, leading to low non-specific protein binding
  • High thermal stability enabling easy sterilization by autoclaving
