WorkBeads affimAb

WorkBeads™ affimAb resin is an optimized alkali-stable resin designed for purification of monoclonal- and polyclonal antibodies in laboratory to process scale. This resin has a superior base matrix in combination with an optimized alkali-stable protein A ligand. This results in high dynamic binding capacity also at short residence times, and stabile capacity over multiple purification cycles with cleaning-in-place using 0.5 M NaOH.
For small scale purifications and initial screening in process development convenient prepacked BabyBio affimAb 1 ml and 5 ml columns are available. WorkBeads affimAb resin can also be used for purifications in other formats, such as batch and centrifugation purifications.

  • Top performance dynamic binding capacity also at short residence times
  • Outstanding alkali stability with 0.5 M NaOH, extends the number of purification cycles
  • Excellent purity, recovery and reproducibility
  • Negligible protein A leakage
  • Convenient prepacked 1 ml and 5 ml BabyBio™ columns
Resin description

WorkBeads are agarose based chromatographic resins manufactured by a proprietary method that results in porous beads with a tight size distribution and very high mechanical stability. Agarose based matrices have been successfully used for decades in biotechnology research from laboratory to production scale, due to their exceptional compatibility with biomolecules including proteins, peptides, nucleic acids and carbohydrates. WorkBeads resins are designed for separations requiring optimal capacity and purity.

The alkali stable recombinant protein A attached to the optimized basematrix is produced in E. coli under conditions free of components of animal origin and purified to high purity before coupling. This combination gives both high dynamic binding capacities for antibodies and the possibility for efficient cleaning-in-place with 0.5 M NaOH.
