Isotopic Amplification, H/D Exchange, and Other Mass Spectrometric Strategies for Characterization mapped by mass spectrometry. First, isotopic amplification of proteins, achieved by expression from growth media doubly-depleted in carbon-13 and nitrogen-15, narrows, amplifies, and shifts the isotopic mass distribution, to identify definitively the „monoisotopic“ species (i. e., the only species w琐碎 发表于 2025-3-25 10:10:16

Studying Noncovalent Small Molecule Interactions with Protein and RNA Targets by Mass Spectrometry,tical research. To develop new therapies at an increasing pace, more new drugs need to be synthesized or discovered, more novel macromolecular targets need to be identified, and compounds need to be characterized, screened and evaluated at a faster rate.

Identification of Protein-Protein Interfaces by Amide Proton Exchange Coupled to MALDI-TOF Mass Spees. The method has broad application to the study of protein conformation and folding and to the study of protein-ligand interactions and requires no modifications of the instrument. Amide protons were allowed to exchange with deuterons in buffered D.O, pD 7.25 at room temperature. Exchanged deutero惰性气体 发表于 2025-3-25 21:55:13

Towards an Integrated Analytical Technology for the Generation of Multidimensional Protein Expressit expressed by a tissue or differentiated cell . In the most commonly used approach to proteome analysis the proteins extracted from the cell or tissue to be analyzed are separated by high resolution two dimensional gel electrophoresis (2DE), detected in the gel by staining or, if radiolabeled, b仔细阅读 发表于 2025-3-26 11:28:39
Sequencing the Primordial Soup,ar protein differences between whole cells (diseased vs. healthy) or between other complex biological fluids are important to understanding protein function.
