Hydroxyl Radical Protein Footprinting Products & Services
GenNext has pioneered a superior, compact, cost-effective, and safe means of performing Hydroxyl Radical Protein Footprinting (HRPF) analysis by replacing expensive, complicated, and hazardous lasers with our proprietary Flash Oxidation (Fox®) Protein Footprinting System in a convenient benchtop format.
To address reproducibility challenges, GenNext has developed the Fox Radical Dosimeter — the world’s first OH radical measurement system that automatically controls the generation of effective OH radicals in the face of unpredictable and varying background scavenging. The Fox Dosimeter provides real-time measurement of OH radical concentration, making it simple to detect problems with biopharmaceutical solutions or assay conditions before mass spectrometric analysis is performed, vastly improving HRPF ease of use while simultaneously ensuring labeling confidence and fidelity.
To eradicate present-day bioinformatics and data processing bottlenecks, GenNext offers FoxWare® Data Processing — a unique data processing program specifically tailored to aptly address and automate data processing demands of HRPF HOS analysis.
Learn how our products can easily fit into your lab’s workflow or test-drive the Fox System on an outsourced project basis.
Hydroxyl Radical Protein Footprinting (HRPF) Services in Monoclonal Antibody Design & Production
HRPF is a powerful technique that is being used to generate high-value information for characterizing monoclonal antibodies (mAb) in the design and development of effective and safe biologics. Researchers are using this technique to study antigen-binding sites, epitope/paratope mapping, host antibody responses, antibody aggregation, and more.
In monoclonal antibody design, researchers are using the high-resolution structural information generated from HRPF for epitope and paratope mapping to accelerate the rational design of therapeutics. In monoclonal antibody production, researchers are using 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, which employs the HRPF approach, provides dynamic, in-solution structure and interaction information for a wide range of protein sizes, states, and concentrations.

Dr. Lisa Jones of UCSD to lead our R&D efforts into in vivo proteins as Cheif Science Officer
Dr. Lisa Jones, GenNext’s new Chief Science Officer (CSO), will lead the expansion of our Flash Oxidation (Fox) Protein Footprinting System into in vivo proteins. Under her direction, we are developing technology to study the protein interactions of membrane proteins, the largest class of drug targets. As director of the Jones Lab at UCSD, her team uses biochemical, analytical, and biophysical approaches coupled with mass spectrometry to identify protein interactions. Dr. Jones is the world-recognized pioneer of in-cell and whole-organism Fast Photochemical Oxidation of Proteins (FPOP). Read her JASMS profile article here.

Meet the GenNext Scientific Advisory Board
Meet Professor David Tabb
Hear what Dr. Tabb from the Institut Pasteur has to say about key innovations in hardware and software that have transformed proteomics. And learn why revealing biological information with the right tools, removing roadblocks caused by black boxes, and continued bioinformatics education are important themes in his research. Then, he discusses why he joined the Scientific Advisory Board to help better understand the datasets produced by GenNext systems that probe protein structure.
Meet Professor Lisa Jones
Professor Lisa Jones invented in-cell and in-vivo Fast Photo-Oxidation of Proteins (FPOP) to study cells and more complex model systems that could not be analyzed by Hydrogen Deuterium Exchange. Taking advantage of irreversible labeling, Lisa’s lab began to use FPOP to study disease pathogenesis in a new way. Most recently, her team is using FPOP to elucidate protein aggregation in different disease states.
