Downstream Processing and Antibody Conjugations

We have the experience and capability to produce and process biological material in milligram to multi-gram quantities. With facilities for both mammalian and microbial cell culture we can process whole cells, cell fragments, cellular extracts or secreted products using your existing protocols; or by developing new, validated procedures. We use a combination of chromatographic techniques for protein purification. These include ion exchange, affinity, size-exclusion and hydrophobic interaction chromatography.

Our expertise extends from routine immunoglobulin purification to process development and downstream processing for novel recombinant protein production.

Our downstream processing services include:

  • Isolation and characterisation of purified proteins from mammalian cells (e.g. monoclonal antibodies, antibody fragments, recombinant proteins)

  • Supply of partially purified or fully purified proteins in accordance with your requirements

  • Conjugation of reporter molecules to purified proteins

  • Isolation and characterisation of purified proteins from microbial cells or supply of cell mass, cell fragments or extracts (enzymes, protein lysate fractions or other intracellular products)
