Abstract: Systems and methods of in vivo and in vitro radical protein foot-printing using an opto-fluidic array are presented. These teachings may be used to, for example, study three-dimensional protein structure or bio-kinetics. Radical dosimetry including an optional intrinsic standard is used. Real-time feedback based on an internal standard provides comparability between different experiments and in vivo and in vitro analysis results in data that is representative of actual biological conditions.

Abstract: Systems and methods of in vivo hydroxyl radical protein foot-printing are presented. These teachings may be used to, for example, study three-dimensional protein structure or bio-kinetics. Radical Dosimetry including an optional intrinsic standard is used on isolated intact cells. Real-time feedback based on an internal standard provides comparability between different experiments and in vivo analysis results in data that is representative of actual biological conditions.

Abstract: Flash Photo-Oxidation Device and Higher Order Structural Analysis is employed for higher order structural analysis of biomolecules. Biomolecular higher order structure (HOS) results from the confounded superimposition of a biomolecule's secondary, tertiary, and quaternary structure and defines the manner in which a biomolecule presents itself and interacts with other biomolecules in living systems. A rapidly growing class of therapeutic drugs, known as biotherapeutics, comprises a variety of proteins, whose therapeutic properties are inherently linked and dependent upon their HOS. As such, HOS analysis of biotherapeutics is an important analytical requirement in the biopharmaceutical industry.

Abstract: The three-dimensional structural analysis of pharmaceutical and/or biological molecules is performed by the reaction of OH radicals on the surfaces of the molecules of interest. Quantitation and/or completeness of the OH radicals are optionally measured using buffers intrinsic to the sample solutions as internal standards. Measurements of the reactions of these buffers with OH radicals provide an internal standard while avoiding the use of prior art internal standards that can have unwanted effects on the three-dimensional structures of interest.
