Magnetic Affinity BioScience Beads are:

  • Faster and more cost-effective than traditional column affinity chromatography,
  • Don't require columns or fraction collectors
  • Made with biotechnology-grade agarose,
  • Filled with micronized magnetic particles immobilized in the gel, and
  • Don't exhibit non-specific binding like some other magnetic beads.

As a result, they have all the advantages of traditional agarose affinity methods plus the advantage of being able to be quickly localized or retrieved with a magnet. This substantially shortens each step in the affinity purification process : exposure to sample, washing off un-bound sample components and finally washing the target componet free of the Iigand on the bead.

Affinity binding and desorption kinetics take place in a fraction of the time required for slow column elution of solute-containing liquids. For a review of these kinetics, see " Analysis of Macromolecular Interactions Using Immobilized Ligands", by Irwin Chaiken, Sergio Rose and Robert Karlsson, in Analytical Biochemistry, 201, 197-210 (1992). Using a magnetic bioseparation technique minimizes the time required for target substance recovery . Magnetic bioseparation can also avoid the unecessary dilution often introduced by typical column elution procedures.

Unlike some magnetic beads, agarose magnetic beads exhibit no non-specific binding and are easily kept suspended with gentle mixing.

Magnetic Agarose Beads are typically used in all of the following formats:

  • microtiter plate(s),
  • test tube(s),
  • beaker(s), and
  • bioreactor(s).

Before using magnetic glass or magnetic plastic beads from other suppliers, it's advisable to consult the following, benchmark publication and many others like it which have appeared more recently:

"Quantitation of Protein Absorbance to Glass and Plastics.." by Paul Christensen, Arne Johansson and Villy Nielsen, Journal of Immunological Methods, 23 (1978) 23-28.

Inquire for attractive reseller bulk discounts. All custom orders receive custom product numbers. Magnetic agarose beads are typically made at either a 4% or 6% agarose concentration. Agarose concentrations from 1-8% are also obtainable in a magnetic format but are considered custom orders which are priced individually if not 4 % or 6% agarose.
