Primary kinetic isotope effect
WebThe marriage between immunology and cytometry is one of the most stable and productive in the recent history of science. A rapid search in PubMed shows that, as of March 2024, using "flow cytometry immunology" as a search term yields more than 60,000 articles, the first of which, interestingly, is not about lymphocytes. WebMass spectrometers ionize an analyte, giving it a positive or negative charge. Due to its charge, the analyte, now an ion, can be easily manipulated by an electromagnetic field, providing that field is essentially void of other species and allows wide spacing of the ions from each other, i.e. under vacuum about 10-11 torr for gas chromatography mass …

WebCarbon kinetic isotope effects (KIEs) at natural abundances during photolysis of Fe 3+-oxalato, malonato, and succinato complexes in aqueous solution were studied to identify the C C bond cleaving mechanism of Fe 3+-oxalato complexes under sunlight irradiation.Observed overall KIEs were 5.9‰, 11.5‰, and 8.4‰, respectively. WebSecondary isotope effects result from changes in the densities of states. Intermolecular secondary isotope effects can be larger than primary effects. The larger the critical …
WebSep 26, 2015 · Isotope labeling experiments (ILEs) are increasingly used to investigate the functioning of metabolic systems. Some enzymes are subject to kinetic isotope effects (KIEs) which modulate reaction rates depending on the isotopic composition of their substrate(s). KIEs may therefore affect both the propagation of isotopes through …
