Lambris, Sheng Li, Sarah Urata
The spreadsheet file reported herein provides centroid data, descriptive of deuterium uptake, for the Fab Fragment of NISTmAb (PDB: 5K8A) reference material, as measured by the bottom-up hydrogen-deuterium exchange mass spectrometry (HDX-MS) method. The

Targeting hMSC Response via Surface Carbonyl Groups, Contact Angle, and Protein Interactions

March 1, 2019
Author(s)
Max J. Lerman, Shinichiro Muramoto, Navein Arumugasaamy, Michael Van Order, Josephine Lembong, Anushka Gerald, John G. Gillen, John P. Fisher
Traditional 2D culture systems made of polystyrene (PS) require the addition of surface chemistry beyond the nominal phenyl groups present to facilitate and encourage cell adhesion. Determining the surface properties which enhance protein adhesion from

Progress and Challenges in Ocean Metaproteomics and Proposed Best Practices for Data Sharing

January 31, 2019

Mak Saito, Erin Bertrand, Megan Duffy, David Gaylord, Noelle Held, Judson Harvey, Robert Hettich, Pratik Jagtap, Michael G. Janech, Danie Kinkade, Dasha Leary, Matt McIlvin, Eli Moore, Robert Morris, Ben Neely, Brook Nunn, Jaclyn Sanders, Adam Shepherd, Nick Symmonds, David Walsh
Ocean metaproteomics is an emerging field that provides an exciting new datatype with potential to enable discoveries regarding marine microbial communities and their underlying impact on global biogeochemical processes. For example, recent ocean

The integration of emerging omics approaches to advance precision medicine: How can regulatory science help?

December 6, 2018
Author(s)
Mark S. Lowenthal, Christina M. Jones, Joan Adamo, Robert Bienvenu, Owen Fields, Soma Ghosh, Michael Liebman, Robert Schuck, Scott Steele
Building on the recent advances in next-generation sequencing, the integration of genomics, proteomics, metabolomics, and other approaches hold tremendous promise for precision medicine. The approval and adoption of these rapidly advancing technologies and

Harmonization of LC-MS/MS protein assays

September 24, 2018
Author(s)
Alan L. Rockwood, Mark Lowenthal, Cory Bystrom
Harmonization of diagnostic test results is fundamental to the effective use of laboratory testing in the diagnosis, treatment and monitoring of disease. Formal approaches to harmonization and standardization provide a rigorous and high quality Roadmap to

C3a receptor antagonism as a novel therapeutic target for chronic rhinosinusitis

June 15, 2018
Author(s)
Jennifer K. Mulligan, Tucker Williamson, Nicholas Reaves, William Carroll, Sarah Stephenson, Peng Gao, Richard R. Drake, Ben Neely, Rodney J. Schlosser, Carl Atkinson
Background: Innate immune factors, including the complement system, have been implicated in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP). Here we examine complement activity within the respiratory mucosa of CRSwNP patients, and a

The role of mass spectrometry in the characterization of biologic protein products

April 25, 2018
Author(s)
Deepali Rathore, John E. Schiel, Anneliese Faustino, Eric Pang, Michael Boyne, Sarah M. Rogstad
Introduction: Mass spectrometry (MS) is widely used in the characterization of biomolecules including peptide and protein therapeutics. These biotechnology products have seen rapid growth over the past few decades and continue to dominate the global

The NISTmAb Tryptic Peptide Spectral Library for Monoclonal Antibody Characterization

March 6, 2018
Author(s)
Qian Dong, Yuxue Liang, Xinjian Yan, Sanford Markey, Yuri Mirokhin, Dmitrii V. Tchekhovskoi, Tallat H. Bukhari, Stephen E. Stein
We describe the creation of a mass spectral library composed of all identifiable spectra derived from the tryptic digest of a therapeutic monoclonal antibody. The NISTmAb library is a unique reference peptide spectral library developed from a total of six

Assessment of extracellular vesicles purity using proteomic standards

September 26, 2017
Author(s)
Tingting Wang, Kyle Anderson, Illarion Turko
The increasing interest in extracellular vesicles (EVs) research is fueled by reports indicating their unique role in intercellular communication and potential connection to the development of common human diseases. The unique role assumes unique protein

The Hybrid Search: A Mass Spectral Library Search Method for Discovery of Modifications in Proteomics

April 3, 2017
Author(s)
Meghan C. Burke, Yuri A. Mirokhin, Dmitrii V. Tchekhovskoi, Sanford P. Markey, Stephen E. Stein, Jenny Heidbrink Thompson, Christopher Larkin
We present a mass spectral library based method to identify tandem mass spectra of peptides that contain unanticipated modifications and amino acid variants. We describe this as a ‘hybrid’ method since it combines matching both ion m/z and mass losses. The

Measurements of translation initiation from all 64 codons in E. coli

February 21, 2017
Author(s)
Ariel H. Hecht, Jeff E. Glasgow, Paul Jaschke, Lukmaan Bawazer, Matthew S. Munson, Jennifer R. Cochran, Drew Endy, Marc L. Salit
Our understanding of translation represents a cornerstone of molecular biology and underpins our capacity to engineer living matter. For decades, the codon AUG and a few near-cognates (GUG, UUG) have been exclusively considered as “start codons” for

A new approach to assess mAb aggregation

January 1, 2001
Author(s)
Illarion Turko
A proof-of-concept for new methodology to detect and potentially quantify mAb aggregation is presented. Assay development included using an aggregated mAb as bait for screening of a phage display peptide library and identifying those peptides with random
