Author(s)
Joshua A. Imperatore, Caylee L. Cunningham, Kendy A. Pellegrene, Robert Brinson, John Marino, Jeffery D. Evanseck, Mihaela R. Mihailescu
The ongoing COVID-19 pandemic highlights the necessity for a more fundamental understanding of the coronavirus life cycle. The causative agent of the disease, SARS-CoV-2, is being studied extensively from a structural standpoint in order to gain insight

Grand Challenges in Pharmaceutical Research Series: Ridding the Cold Chain for Biologics

February 8, 2021
Author(s)
Yihua B. Yu, Katharine T. Briggs, Marc B. Taraban, Robert Brinson, John Marino
Biologics are complex pharmaceuticals that include formulated proteins, plasma products, vaccines, cell and gene therapy products, and biological tissues. These products are fragile and typically require cold chain for their delivery and storage

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

Characterization of the internal translation initiation region in monoclonal antibodies expressed in Escherichia coli

October 11, 2019
Author(s)
Erik M. Leith, William Brad O'Dell, Na Ke, Colleen McClung, Mehmet Berkmen, Christina Bergonzo, Robert G. Brinson, Zvi Kelman
Monoclonal antibodies (mAbs) represent an important platform for the development of biotherapeutic products. While most mAbs are produced in mammalian cells, there are several examples of mAbs made in Escherichia coli, including therapeutic fragments. When

Structural Insights into DNA-Stabilized Silver Clusters

May 10, 2019
Author(s)
Danielle Schultz, Robert G. Brinson, Fahriye N. Sari, Jeffrey Fagan, Christina Bergonzo, Nancy Lin, Joy Dunkers
The structure and dynamics of Ag complexes derived from single stranded DNA (ssDNA) is less understood than their double stranded (dsDNA) counterparts despite their great promise as fluorescent biological probes and sensors. In this work, we seek new

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