With a wealth of experience in the Drug Discovery environment, we are confident our team can fulfil your needs for any part of the Gene to Structure process.

We tailor our professional services to fit your requirements, whatever stage of the process you are at.  From construct design, through to expression and purification of your desired protein. Whatever your end use, assay, high throughput screening, biophysics or crystallisation and X-ray structure determination, we can supply your protein in a suitable format.

Peak Proteins’ Services

Protein Expression and Purification

We design, express and purify customised proteins reagents to support all stages of the drug discovery process. Our cell and protein scientists have a wealth of experience, many from large pharma organisations. We have many peer reviewed publications describing these techniques. We apply all our expertise and knowledge to your protein, providing an interactive, innovative and flexible approach to every project. Every protein and end use is different. We provide a tailored service, taking the time to understand your specific needs to deliver success. We express proteins using a range of platforms including mammalian HEK293 suspension cells, baculovirus/insect cells, and E. coli.

Protein Crystallography and Structure Determination

Our protein structure determination service is driven by an outstanding team of experienced crystallographers with a strong publication record in solving a wide variety of protein structures, including novel ones. A key part of this process is the design of the protein and the ability to screen many different constructs and crystallisation conditions. Our final delivery package is not just a set of co-ordinates. We supply a detailed analysis of the overall 3D structure, along with our learning and conclusions, with ideas for project progression and drug design. Interactive discussions and regular communication with our clients are a key part of our service.

Protein Mass spectrometry

We now provide intact protein and peptide mapping as a stand-alone service to anyone requiring detailed protein or antibody characterisation.  Key to this service is the flexibility and quick turnaround times we offer with no detailed contract set-up. Our expert mass spectrometrist, Rachel Rowlinson, will initially discuss your specific needs. Help will be giving with planning and interpretation of the samples analysed and a comprehensive data summary package will be provided with follow-up discussion if required. Whether you have one sample or larger numbers on a regular basis will be reflected in our pricing.

Time critical purification of multiple Fab constructs for assay

Time critical purification of multiple Fab constructs for assay As a leading protein purification company, BiVictriX required us to develop a method to purify 10mg each of 24 different antibody-binding fragments (Fabs) to be tested in assays. Once analysed by BiVictriX, a smaller number of chosen constructs were to [...]
