Protein Expression Facility (PEF)

The Protein Expression Facility (PEF) provides a recombinant expression and purification service to the University of Birmingham Research community.

As part of the Technology hub the PEF acts as a focal point for advice about all aspects of recombinant protein production. The expression systems used by the PEF will enable the recombinant proteins generated to be used in a wide range of downstream applications.

Why work with us?

Equipment in the Protein Expression Facility (PEF)

The PEF provides a service as close to cost price as possible, but consistent with facility sustainability. The PEF aims to cater for the production of a wide variety of proteins to enable a comprehensive range of downstream technologies and to be responsive to customer needs where possible.

The PEF reside within a designated, fully-equipped laboratory suite that was funded by a central infrastructure bid in 2010 through the College of Medical and Dental Sciences.

The PEF is self-funded, with annual running costs met through recharging schemes proportional to the level and nature of collaboration. Activities are distributed across the Birmingham campus research community, but the PEF welcomes collaboration with Midlands Innovation and external companies.

The PEF provides a central location to undertake recombinant protein expression within a dedicated environment. It also provides a range of expression and purification services or training which can be commissioned at any time.

Who do we work with?

The Protein Expression Facility (PEF) at the University of Birmingham is available to the following groups:

- Current staff and students

- Prospective staff and students

- Academics both internal and external

- Industry professionals

Expression and Purification Facility

The PEF offers a one stop shop for small scale test expressions through to medium scale expressions followed by purification and polishing of the protein requested.

The service provided may be inclusive of cloning, optimisation of the construct via test expression through to scaling up for purification and polishing, or may be a Principal Investigators well characterised protocol. Work undertaken will depend on the initial discussions to outline the project requirements and the status of existing Biosafety approvals.

The PEF offers expertise in E.coli, mammalian cell and insect cell expression and has two dedicated culture facilities. One is dedicated to prokaryotic work and has three programmable incubators capable of growth conditions between 4-80 degrees with two dedicated Beckman Avanti centrifuges. The eukaryotic culture facility hosts incubators for static, shaking and roller bottle culture of mammalian or insect cell.

MHC class I refolds

The PEF routinely makes HLA A0101, HLA A0201, HLA B8 and HLA B7 and holds a supply of the inclusion bodies used to refold the peptides chosen by the customer.Biotinylated MHC Class I Monomer are composed of a particular peptide in combination with a particular MHC class I allele that has been biotinylated at the C-terminus of the heavy chain extracellular domain. The Biotinylated Class I MHC/peptide complex can be used in research studies using the MHC tetramer assay and the PEF has been routinely supplying the Birmingham Researcher with monomers since 2010.

For more information regarding how to get in touch with the PEF about Biotinylated MHC Class I Monomer production, please use the contact details at the bottom of this webpage 

Current Research

Currently the facility is collaborating across campus on a range of expression projects with Institutes in the Medical School, Biosciences, Chemistry and with the Midlands Innovation group of Universities.

The PHERAstar provides collaborative resources for the Birmingham Researcher wishing to read single plate fluorescent or chemiluminescent assay’s and our customer range from Sports and exercise to the Medical school.
