The Next Generation of
Protein HOS Analysis

Reinventing Protein Higher Order Structural Analysis via State-of-the-Art Protein Footprinting

The Fox® Protein Footprinting System employs hydroxyl radicals (•OH) to examine the solvent accessibility of amino acid side chains within a protein. By selectively abstracting hydrogen atoms from exposed amino acids, •OH radicals induce the formation of oxidation products, enabling the detection and analysis of vital information concerning protein structure and dynamics. Automated HRPF, made possible by the Fox System, delivers crucial HOS information that greatly influences the safety, efficacy, and quality of biologics.

Comprised of a user-friendly benchtop instrument coupled with intuitive data analysis software, the Fox System makes it possible for biopharmaceutical researchers to easily and efficiently unravel the mysteries of protein HOS. This powerful tool opens new avenues for studying and understanding proteins, accelerating advancements in biopharmaceutical research and development.

HRPF Services for Monoclonal Antibodies

Let the experienced GenNext research team generate high-value information on the characterization of monoclonal antibodies (mAb) for more effective and safe biologics. Start a project today to study antigen-binding sites, epitope/paratope mapping, host antibody responses, antibody aggregation, and more.

In mAb design, use the high-resolution structural information generated from HRPF for epitope and paratope mapping to accelerate the rational design of therapeutics. In mAb production, use HRPF to monitor mAb structure during scale-up to ensure batch-to-batch structure stability over time, ensuring product shelf life and continued efficacy.

Unlike other protein structure analysis techniques, the Fox Protein Footprinting System delivers dynamic, in-solution structure and interaction information for a wide range of protein sizes, states, and concentrations.
