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 introduces 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.

Meet the GenNext Scientific Advisory Board
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.
Meet Professor Michael Gross
Listen to Professor Michael Gross as he describes the invention of Fast Photo-Oxidation of Proteins (FPOP) for Hydroxyl Radical Protein Footprinting (HRPF). Professor Gross highlights how it is being applied in epitope mapping studies. He anticipates a great future for footprinting in antibody drug development for improved biotherapeutics.
Meet Dr. Mark Chance
Meet the world-famous father of HRPF, Dr. Mark Chance. In this interview, he describes being motivated to develop a new technique to see, with much greater resolution, proteins in motion. Living in the “magical middle ground” of moderate cost and higher resolution, Dr. Chance discusses his lab’s use HRPF technology to study neurological samples to detect the severity of a debilitating disease.
Meet Dr. Joshua Sharp
Watch as Genny™ the GenNext Fox interviews the internationally recognized expert in Hydroxyl Radical Protein Footprinting (HRPF)—Dr. Joshua Sharp. As the inventor of the first benchtop HRPF system and the pioneer of UV photolysis of hydrogen peroxide for hydroxyl radical generation, Josh has a lot of interesting things to say about the current success and future potential of protein footprinting.
