Mass spectrometry enumeration of filamentous M13 bacteriophage

July 2, 2019
Author(s)
Tingting Wang, Ai Nguyen, Linwen Zhang, Illarion Turko
In the last decade, filamentous M13 bacteriophage has emerged into numerous biotechnological applications as a promising nontoxic and self-assembling biomaterial with specific binding properties. This raises a question about its upscale production that

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

Cytochrome P450 27A1 Deficiency and Regional Differences in Brain Sterol Metabolism Cause Preferential Cholestanol Accumulation in the Cerebellum

February 11, 2017
Author(s)
Natalia Mast, Kyle Anderson, Joseph Lin, Yong Li, Illarion Turko, Curtis Tatsuoka, Ingemar Bjorkhem, Irina A. Pikuleva
Cytochrome P450 27A1 (CYP27A1 or sterol 27-hydroxylase) is a ubiquitous, multifunctional enzyme catalyzing regio- and stereo-specific hydroxylation of different sterols. In humans, complete CYP27A1 deficiency leads to cerebrotendinous xanthomatosis or

A new approach to quantification of mAb aggregates using peptide affinity probes

February 10, 2017
Author(s)
Crystal Cheung, Kyle Anderson, Pooja Patel, Keale Cade, Karen W. Phinney, Illarion Turko
Using mAbs as therapeutic molecules is complicated by the propensity of mAbs to aggregate at elevated concentrations, which can lead to a variety of adverse events in treatment. Here, we describe a proof-of-concept for new methodology to detect and

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
