A recent ion mobility spectrometry-mass spectrometry (IMS-MS) study revealed that tryptic peptide ions containing a proline residue at the second position from the N-terminus (i.e., penultimate proline) frequently adopt multiple conformations, owing to the cis-trans isomerization of Xaa(1)-Pro(2) peptide bonds [J. Am. Soc. Mass Spectrom. 2015, 26, 444].(More)
Owing to the remarkable photometric precision of space observatories like Kepler, stellar and planetary systems beyond our own are now being characterized en masse for the first time. These characterizations are pivotal for endeavors such as searching for Earth-like planets and solar twins, understanding the mechanisms that govern stellar evolution, and(More)
Label-free absolute protein quantification refers to a process of estimating protein abundances in complex biological samples based on the data acquired from a liquid chromatography mass spectrometry (LC-MS) analysis. Most approaches to label-free quantification rely on measuring peak areas from an extracted-ion chromatogram. However, because of the(More)
