Description

Seeking scalable flow-through methods to separate monomers from aggregates

Background

The use of proteins as drugs is an important, and growing, sector in the pharmaceutical market. Antibodies, proteins and peptides are used. They are expressed in mammalian cells, grown in large fermenters containing 1000L (or more) of culture media. The target protein is secreted into solution and must be purified.

 

Proteins can aggregate during production. The aggregated protein must be removed from solution. Aggregation reduces the biological activity of proteins and it is critically important that biopharmaceuticals are highly active.

 

We are seeking scalable flow-through methods to separate monomers from aggregates. We are looking at continuous media manufacturing and this technology will help provide additional sterility assurance. We are keen identify partners who can sell, supply or collaborate with us to develop appropriate technology.

 

Key Success Criteria

• Yields of monomer > 70%

• Overall purity of product is maintained

• Works with proteins from approximately 25kDa to 160kDa

 

Possible Approaches

GSK is open to all approaches capable of achieving the criteria set forth above.

 

 

Approaches not of interest

Bind and elute method.

 

 

Preferred Collaboration types
  • Joint Development
  • Contract Research
  • Supply Agreement
