Determination of titer

Affinity chromatography is based on the biospecific interaction between a biomolecule and its ligand. This interaction is reversible, making it possible to isolate specific compounds from complex matrices, such as cell culture used for monoclonal antibody (mAb) production. This approach is used to determine the concentration, or titer, of a biotherapeutic protein during the manufacturing process. Affinity titer is an extremely important technique in the biopharmaceutical industry, being used during several stages of the biotechnological protein production process.

We have a wide range of affinity columns and resins from discovery to QA/QC.
