Protein Production

Key Facts

  • Provision of a guided work flow
  • Microbial, insect and mammalian cell hosts
  • Cell free in vitro expression in various host lysates

Protein Production Core Facility

The Protein Production Core Facility (PPCF) is designed to provide users with the complete infrastructure for protein production using the most modern and efficient methods. Particular attention is paid to maintaining the highest quality standards of the samples to be produced, which guarantees the suitability of the samples for functional and structural studies in a reproducible manner. Additionally, we aim to develop sustainable processes.

Services

The Protein Production Core Facility offers all steps of protein production consisting of the mutagenesis and cloning of target genes in expression vectors, their heterologous expression in prokaryotic and eukaryotic hosts, as well as the subsequent purification of the corresponding proteins as a service. In addition to the full service, in which the employees of the facility carry out the work, the users can carry out the work in the facility under the supervision of the facility team. The service includes advice on the selection of suitable strategies, the provision and optimization of suitable protocols, the instruction and use of the required equipment and the provision of the required vectors, cell lines, chromatography materials and all necessary consumables. The following services are offered in detail:

- Cloning and mutagenesis
- Cultivation of prokaryotic and eukaryotic cells of risk group R2 or security level S2
- Transformation of prokaryotic cells
- Transfection of insect cells and mammalian cells
- High-throughput heterologous expression screening in plate format: E. coli & insect cells
- Heterologous expression in E. coli, insect cells and mammalian cells
- Cell harvest and cell lysis
- Ultracentrifugation and cell membrane isolation
- Protein purification using Äkta Pure chromatography devices
- Development and optimization of protein purification protocols
- Automation of protein purification protocols
- Biochemical characterization (SDS and native PAGE, IEF, Western Blotting)
- Biophysical characterization (stability measurements using microscale thermophoresis)
- E. coli strain collection
- Expression vector collection
- NEB freezer

Further information

The PP facility is operated in close collaboration with the facility for recombinant protein expression at HZI in Braunschweig. The PP at the CSSB Hamburg supports users in small to mid-scale expression experiments in bacterial (E. coli) and insect cells. The HZI facility supports mid- to large-scale heterologous expression in bacterial and eukaryotic hosts. PP at the CSSB Hamburg will also support users in establishing the appropriate expression conditions for mid to large scale expression in the HZI facility. The close collaboration between the two protein production facilities will benefit users involved in challenging expression projects by saving them both time and resources.

Access to the PP services and resources

  • The facility is a fee-for-service (non-profit) technology platform operated by HZI. We provide support and expertise for local scientists, the international research community and users from industry.
  • All users must follow a safety training before working in our laboratories. All users are required to undergo training before access to the individual instruments is granted. Currently the biosafety training is given onsite.
  • Please get in touch with us to discuss your specific needs.
