Daniel A Polasky et al.
Analytical chemistry, 91(4), 3147-3155 (2019-01-23)
Ion mobility-mass spectrometry (IM-MS) has become an important addition to the structural biology toolbox, but separating closely related protein conformations remain challenging. Collision-induced unfolding (CIU) has emerged as a valuable technique for distinguishing iso-cross-sectional protein and protein complex ions through
Jared B Shaw et al.
Analytical chemistry, 90(18), 10819-10827 (2018-08-18)
Compared to traditional collision induced dissociation methods, electron capture dissociation (ECD) provides more comprehensive characterization of large peptides and proteins as well as preserves labile post-translational modifications. However, ECD experiments are generally restricted to the high magnetic fields of FTICR-MS
John P McGee et al.
Journal of the American Society for Mass Spectrometry, 31(3), 763-767 (2020-03-05)
Intact protein mass spectrometry (MS) via electrospray-based methods is often degraded by low-mass contaminants, which can suppress the spectral quality of the analyte of interest via space-charge effects. Consequently, selective removal of contaminants by their mobilities would benefit native MS
Liyun Zhang et al.
Bioanalysis, 10(13), 1039-1054 (2018-06-29)
The requirements for developing antibody biotherapeutics benefit from understanding the nature and relevant aspects of the entire molecule. The method presented herein employs on-line multidimensional LC-quadrupole time-of-flight (QTOF)-MS for the quantitative determination of an antibody isolated from biological samples while
Yutong Jin et al.
mAbs, 11(1), 106-115 (2018-09-20)
The pharmaceutical industry's interest in monoclonal antibodies (mAbs) and their derivatives has spurred rapid growth in the commercial and clinical pipeline of these effective therapeutics. The complex micro-heterogeneity of mAbs requires in-depth structural characterization for critical quality attribute assessment and
"Collision Induced Unfolding Detects Subtle Differences in Intact Antibody Glycoforms and Associated Fragments.
Tian Y and Brandon T R
International Journal of Mass Spectrometry (2017)
Xi Qiu et al.
Bioanalysis, 10(13), 1055-1067 (2018-07-05)
Sample extraction using immuno-affinity capture coupled with LC-high-resolution mass spectrometer has recently emerged as a novel approach for the determination of concentrations of large molecules at intact level in biological matrix. In the current work, different data processing strategies for
Anna C Robotham et al.
mAbs, 11(4), 757-766 (2019-03-22)
The detection of free sulfhydryls in proteins can reveal incomplete disulfide bond formation, indicate cysteine residues available for conjugation, and offer insights into protein stability and structure. Traditional spectroscopic methods of free sulfhydryl detection, such as Ellman's reagent, generally require
