Biochromatography - Affinity Chromatography and Titre Analysis

Affinity chromatography is a powerful technique which takes advantage of highly specific molecular interactions, frequently between specific proteins (e.g. antigen/antibody).

In the biopharmaceutical industry affinity chromatography can be used as one of the processing tools in the production monoclonal antibodies (MAbs). The Protein A column can be used for the following:

  • Clone selection based on MAb titer
  • Fast screening of harvest cell culture samples for IgG – process optimisation
  • Accurate analysis of mAb quantities to determine protein harvest
  • Capture and purification of protein for further characterisation
