Identification of novel N-glycosylation sites at non-canonical protein consensus motifs

June 14, 2016
Author(s)
Mark S. Lowenthal, Kiersta S. Davis, Lisa E. Kilpatrick, Catherine A. Mouchahoir, Karen W. Phinney
N-glycosylation is well known to occur at asparagine residues in the canonical consensus sequence N-X-S/T, but has also been identified at a small number of N-X-C motifs including the Asn491 residue of human serotransferrin. Here we report additional novel

QUANTITY: An Isobaric Tag for Quantitative Glycomics

November 30, 2015
Author(s)
Shuang Yang, Meiyao Wang, Lijun Chen, Illarion Turko, Karen W. Phinney, Shuwei Li
We describe the design and synthesis of a novel set of iso-baric tags for quantitative glycan profiling, which will have broad applications in carbohydrate based biomarker dis-covery, therapeutic protein characterization, and vaccine development.

Quantification of Borrelia burgdorferi membrane proteins in human serum: a new concept for detection of bacterial infection

November 17, 2015
Author(s)
Sao F. Cheung, Kyle Anderson, Kenia Benitez, Mark J. Soloski, John N. Aucott, Karen W. Phinney, Illarion Turko
The low abundance of bacterial proteins in human serum upon infection imposes a challenge for the early proteomic detection of bacterial infection. To address this challenge, we propose to take advantage of detecting membrane proteins released from

QconCAT: Internal Standard for Protein Quantification

October 21, 2015
Author(s)
Kerry M. Bauer, Karen W. Phinney, Illarion V. Turko
Protein quantification based on stable-isotope labeling mass spectrometry (SIL-MS) involves adding known quantities of stable-isotope labeled internal standards into biological samples. The internal standards are analogous to analyte molecules and

Determination of the Primary Sequence/ Structure

October 15, 2015
Author(s)
Catherine A. Mouchahoir, Mellisa Ly, Michaella Levy, Lisa E. Kilpatrick, Scott C. Lute, Karen W. Phinney, Lisa Marzilli, Kurt A. Brorson, Michael T. Boyne, Darryl Davis, John E. Schiel
The primary sequence of a protein, including therapeutic monoclonal antibodies (mAbs), is a critical quality attribute that determines a great deal of its functionality and stability. Significant effort is devoted to determining the complete amino acid

Standardizing 25-Hydroxyvitamin D values from the Canadian Health Measures Survey

September 30, 2015
Author(s)
Kurtis Sarafin, Ramon Durazo-Arvizu, Lu Tian, Karen W. Phinney, Susan Tai, Johanna Camara, Hubert W. Vesper, Joyce M. Merkel, Evan Green, Christopher T. Sempos, Stephen P. Brooks
Background: The Canadian Health Measures survey (CHMS) is an ongoing cross sectional national survey that includes a measure of 25-hydroxyvitamin D (25(OH)D) by Diasorin LIAISON immunoassay. The survey repeats approximately every two years with a new

Influence of Chemical Straightening on the Stability of Drugs of Abuse in Hair

October 8, 2014
Author(s)
Jeanita Pritchett, Karen W. Phinney
Chemical straightening, also known as a relaxer, is ubiquitously used among African American women to obtain straighter hair compared with their natural tresses. This study focused on the stability of drugs of abuse in hair after a single application of
