WorkBeads™ affimAb resin is an optimized alkaline-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 alkaline-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 alkaline 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
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 alkaline 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.
