Interlaboratory Studies using the NISTmAb to Advance Biopharmaceutical Structural Analytics

May 5, 2022
Author(s)
Katharina Yandrofski, Trina Mouchahoir, M. Lorna De Leoz, David L. Duewer, Jeffrey W. Hudgens, Kyle Anderson, Luke Arbogast, Frank Delaglio, Robert Brinson, John Marino, Karen W. Phinney, Michael J. Tarlov, John E. Schiel
Biopharmaceuticals such as monoclonal antibodies are required to be rigorously characterized using a wide range of analytical methods. Various material properties must be characterized and well controlled to assure that clinically relevant features and

Principal Component Analysis for Automated Classification of 2D Spectra and Interferograms of Protein Therapeutics: Influence of Noise, Reconstruction Details, and Data Preparation

July 22, 2020
Author(s)
Robert Brinson, Wade Elliott, Luke Arbogast, David Sheen, John Giddens, John Marino, Frank Delaglio
Protein therapeutics must retain their proper three-dimensional fold without forming aggregates for safe and effective use in the clinic. Therefore, the ability to monitor protein higher order structure (HOS) can be valuable throughout the lifecycle of a

Selective spin inversion in solution by magic field cross polarization

November 1, 2019
Author(s)
Joel Tolman, Luke Arbogast
A pulsed element is proposed allowing the selective inversion of a single 1H nucleus, without regard to the presence of other degenerate 1H nuclei, provided that it is coupled to a heteronuclear spin with adequate chemical shift resolution in a 2D

Enabling adoption of 2D-NMR for the higher order structure assessment of monoclonal antibody therapeutics

January 1, 2019
Author(s)
Robert G. Brinson, John P. Marino, Frank Delaglio, Luke W. Arbogast, Ryan M. Evans, Anthony J. Kearsley, Yves Aubin, Gregory Pierens, Xinying Jia, David Keizer, Jonas Stahle, Goran Widmalm, Chad Lawrence, Patrick Reardon, John Cort, Koichi Kato, Stuart Parnham, Andreas Blomgren, Torgny Rundlof, Kang Chen, David Keire, Thea Suter-Stahel, Gerhard Wider, Donna Baldisseri, Julie Wu, Mats Wikstrom, Medhi Mobli
Of the top ten drugs on the global market in 2016, seven of them are biologics with a combined market value of over US$60 billion. Moreover, around 2,800 biopharmaceuticals, many of them monoclonal antibodies (mAbs), are in some stage of clinical

Non-Uniform Sampling for All: More Spectral Quality, Less Measurement Time

June 30, 2017
Author(s)
Frank Delaglio, Gregory S. Walker, Kathleen A. Farley, Raman Sharma, Jeffrey C. Hoch, Luke Arbogast, Robert Brinson, John Marino
Nuclear Magnetic Resonance (NMR) spectroscopy is an indispensable tool in pharmaceutical science, with uses in drug discovery, development, and manufacturing. Non-Uniform Sampling (NUS) is an acquisition method for NMR experiments with two or more

Current and Emerging Technologies to Characterize the Higher-Order Structure of Monoclonal Antibodies

October 15, 2015
Author(s)
John Marino, Robert G. Brinson, Jane E. Ladner, David Travis Gallagher, Luke Arbogast, Richard Huang, Jeffrey W. Hudgens, Elyssia S. Gallagher
In contrast to small molecule therapeutics whose conformations can be absolutely defined by constitution and stereochemistry, biopharmaceuticals are distinguished by the requirement for folding into higher order structures (secondary, tertiary, and

2D 1HN, 15N Correlated NMR Methods at Natural Abundance for Obtaining Structural Maps and Statistical Comparability of Monoclonal Antibodies

March 1, 2015
Author(s)
Luke Arbogast, Robert G. Brinson, Catherine A. Mouchahoir, James T. Hoopes, John Marino
Purpose High-resolution nuclear magnetic resonance spectroscopy (NMR) provides a robust approach for producing unique spectral signatures of protein higher order structure at atomic resolution. Such signatures can be used as a tool to establish consistency

Mapping Monoclonal Antibody Structure by 2D 13C NMR at Natural Abundance

March 1, 2015
Author(s)
Luke Arbogast, Robert G. Brinson, John Marino
Monoclonal antibodies (mAbs) represent an important and rapidly growing class of biotherapeutics. Correct folding of a mAb is critical for drug efficacy, while misfolding can impact safety by eliciting unwanted immune or other off-target responses. Robust
