Comprehensive Analysis of Tryptic Peptides Arising from Disulfide Linkages in NISTmAb and Their Use for Developing a Mass Spectral Library

June 22, 2021
Author(s)
Qian Dong, Xinjian Yan, Yuxue Liang, Sanford Markey, Sergey L. Sheetlin, Concepcion Remoroza, William E. Wallace, Stephen Stein
This work presents methods for identifying and then creating a mass spectral library for disulfide-linked peptides originating from the NISTmAb. Analysis involved both partially- reduced and non-reduced proteins under neutral and weakly basic conditions

Mass Spectral Library of Acylcarnitines Derived from Human Urine

April 8, 2020
Author(s)
Xinjian Yan, Sanford Markey, Ramesh Marupaka, Qian Dong, Brian T. Cooper, Yuri Mirokhin, William E. Wallace, Stephen Stein
We describe the creation of a mass spectral library of acylcarnitines and conjugated acylcarnitines from the LC–MS/MS analysis of six NIST urine reference materials. To recognize acylcarnitines, we conducted in-depth analyses of fragmentation patterns of

Mass Spectrometry Fingerprints of Small-Molecule Metabolites in Biofluids. Building a Spectral Library of Recurrent Spectra for Urine Analysis.

August 19, 2019
Author(s)
Yamil Simon, Ramesh Marupaka, Xinjian Yan, Yuxue Liang, Kelly H. Telu, Yuri A. Mirokhin, Stephen E. Stein
A large fraction of ions observed in electrospray liquid chromatography-mass spectrometry (LC-MS) experiments of biological samples remain unidentified. One the main reasons for this is that spectral libraries of pure compounds fail to account for the

The NISTmAb Tryptic Peptide Spectral Library for Monoclonal Antibody Characterization

February 9, 2018
Author(s)
Qian Dong, Yuxue Liang, Xinjian Yan, Sanford P. Markey, Yuri A. 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

A Description of the Clinical Proteomics Tumor Analysis Consortium (CPTAC) Common Data Analysis Pipeline

February 10, 2016
Author(s)
Jeri S. Roth, Paul A. Rudnick, Sanford Markey, Yuri Mirokhin, Xinjian Yan, Dmitrii Tchekhovskoi, Stephen Stein, Nathan J. Edwards, Ratna R. Thangudu, Karen A. Ketchum, Christopher R. Kinsinger, Mehdi Mesri, Henry Rodriguez
The Clinical Proteomic Tumor Analysis Consortium (CPTAC) has produced large proteomics datasets from the mass spectrometric interrogation of tumor samples previously studied by The Cancer Genome Atlas (TCGA) program. The availability of the genomic and

Metabolite Profiling of a NIST Standard Reference Material for Human Plasma (SRM 1950) – GC/MS, LC/MS, NMR and Clinical Laboratory Analyses, Libraries and Web-based resources

October 22, 2013
Author(s)
Yamil Simon, Mark S. Lowenthal, Lisa E. Kilpatrick, Maureen L. Sampson, Kelly H. Telu, Paul A. Rudnick, William G. Mallard, Daniel W. Bearden, Tracey B. Schock, Dmitrii V. Tchekhovskoi, Niksa Blonder, Xinjian Yan, Yuxue Liang, Yufang Zheng, William E. Wallace, Pedatsur Neta, Karen W. Phinney, Alan T. Remaley, Stephen E. Stein
Recent progress in metabolomics and the development of increasingly sensitive analytical techniques have renewed interest in global profiling, i.e., semi-quantitative monitoring of all chemical constituents of biological fluids. In this work, we have

Uncertainty Reporting for Experimental Thermodynamic Properties

January 1, 2005
Author(s)
Qian Dong, Robert D. Chirico, Xinjian Yan, X Hong, Michael D. Frenkel
This paper reviews practices in the expression of uncertainty in the experimental literature for thermodynamic property measurements with determinations of critical temperature for pure compounds used as a case study. The time period considered is from
