Peak Protein Services

We are a contract research organisation, part of  Sygnature Discovery; who provide custom-made, soluble and membrane proteins for use in drug discovery and research applications as well as X-ray, NMR and Cryo-EM structures of both novel and precedented proteins.

Protein Expression and Purification

Protein Expression and Protein Purification

We design, express, and purify customised soluble and membrane proteins reagents to support your research needs. We apply our expertise and knowledge to your protein of interest to provide an innovative, interactive, and flexible approach to every project.

Protein Mass Spectrometry

Protein Characterisation

We use various methods to characterise and quality control the proteins we make. We also offer some of these as standalone services to our clients, including intact protein mass spectrometry and peptide mapping, Flow induced dispersion analysis (Fida) and NMR.


Protein Crystallography and Structure Determination

Structural Biology

Providing crystallography, Cryo-EM and NMR, our service isn’t just a final set of co-ordinates, but a detailed analysis of the 3D structure along with our learning and conclusions, driving ideas for project progression and drug design.

Working with us?

We provide high quality protein reagents and structural data to help you achieve your goals. You will be working with a CRO who is responsive and fully engaged in your project. We offer both FFS and FTE flexible contract models. Find out more about working with us here.
