Recombinant Protein Capabilities
Accelerate Drug Discovery with Reliable and High-quality Proteins – Better Targets for Better Drugs
Producing high-quality, functional proteins for hit finding, antibody development, and structural studies is a complex process requiring precision, scientific expertise coupled with innovative techniques, and seamless project coordination. Trust Eurofins CALIXAR’s protein development capabilities to deliver high-quality functional recombinant proteins for your early drug discovery programs and save time by significantly increasing your drug targets’ chances of clinical trials success.
Eurofins CALIXAR, the protein center of excellence part of Eurofins DiscoverX®, offers fully integrated custom protein production capabilities that can handle every stage of protein development in-house — from construct design to expression, purification, and functional validation. This approach assures that high-quality, functional proteins are delivered, eliminating the need for rework or switching providers. Streamlined processes ensures that the native fold, any post-translational modifications, and protein functionality are preserved within the native binding pockets and epitopes are maintained.
Eurofins CALIXAR recombinant protein capabilities team specializes in producing a wide range of proteins, including membrane proteins (such as GPCRs, ion channels, and transporters) and soluble proteins (like kinases, phosphatases, epigenetic proteins, and other enzymes), supporting various applications for both small molecule (hit identification and screening), large molecules (antibody development including immunization and library screening), and 3D structure-based drug design. With over a decade of experience, Eurofins CALIXAR’s advanced technologies and scientific expertise ensure consistent quality and reliable recombinant protein expression, minimizing risks and enabling your research and drug discovery to stay on track.
