AT Protein A Diamond Ultra is an innovative affinity resin made by coupling alkali-resistant Protein A with a high-rigidity agarose matrix. The optimized resin pore size helps with the increasing in binding capacity of the antibody. The resin is suitable for capturing monoclonal antibodies or Fc fusion proteins from a large amount of cell culture media, as well as polyclonal antibodies from ascites fluid or plasma.
The resin can be cleaned in place with 0.1-0.5M NaOH, which avoids the use of expensive and corrosive cleaning reagents, effectively cutting costs. In addition, compared with AT Protein A Diamond Plus, the new resin enjoys higher binding capacity, as well as lower production cost due to the smaller CV selected in scale-up process.
The resin has the following characteristics:
High rigidity, low back pressure and fast flow velocity, suitable for large-scale production applications.
High binding capacity, reduce production costs.
Good alkaline tolerance, longer service life.
