We tested MSBooster on single-cell data from the nanoPOTS platform67 generated using an Orbitrap Fusion Lumos Tribrid instrument with HCD fragmentation. Briefly, we analyzed the data obtained from 1, 3, 10, or 50 cells. Single-cell MS/MS spectra differ from bulk-cell spectra in terms of ...
Peptide fragmentation spectra are routinely predicted in the interpretation of mass-spectrometry-based proteomics data. However, the generation of fragment ions has not been understood well enough for scientists to estimate fragment ion intensities accur
The reduced fragmentation of the NH4+spectra makes the technique better suited for untargeted analysis. 使用NH4+试剂离子,Vocus CI质谱仪可以直接测量呼吸中低浓度的代谢物和其他化合物,且相对于PTR模式而言,电离过程中碎片率大大降低。图9中展示了Vocus CI-MS对某志愿者呼出气体分别在H3O+ (PTR)和NH4+试剂...

Key words:amoxicillinrelated substancesUPLC-TOF-MS/MSfragmentation regularity 阿莫西林又名安莫西林、安默西林,是一种常用的青霉素类广谱β内酰胺类抗生素,为一种白色粉末,半衰期约为61.3 min。阿莫西林在高温、光照、酸、碱和氧化条件下会发生降解,生成阿莫西林的相关产物。临床上证实阿莫西林的聚合物会引起过敏反应,所...
Gas phase fragmentations of the intact cation of carnitine are strikingly different from those observed in the SIMS spectrum, in contrast to the behavior of thiamine, cocaine and candicine for which collision-induced dissociations provide a good guide to desorption ionization mass spectra. 展开 ...
