Boston-based PerkinElmer Life and Analytical Sciences has released the prOTOF™ 2000, the first commercially available matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass ...

Homology surveillance of carbapenem-resistant Klebsiella pneumoniae (CRKP) is critical to monitor and prevent outbreaks of nosocomial infections. In the present study, a matrix-assisted laser ...

The inimitable adaptability of MALDI-TOF/TOF systems enables tissue imaging of intact proteins, as well as of tryptic peptides brought about by on-tissue digestion. Although intact protein imaging can ...

MALDI-TOF MS有效鉴定环境军团菌属（L. anisa、L. longbeachae、L. pneumophila）物种，24小时培养结合直接转移法最佳，灵敏度94.6%-100% ...

Perhaps no tool has been as instrumental to the proteomics revolution as the mass spectrometer. With the ability to deconvolute highly complex mixtures over a wide range of abundance levels, these ...

直接MALDI-TOF MS快速鉴定病原体在血液等无菌体液中的应用研究，发现其可在30-60分钟内完成病原体鉴定，但存在革兰氏阴性菌识别率高于阳性菌及真菌的现象，主要受样本中微生物浓度、细胞壁结构及蛋白质提取效率影响，同时面临低灵敏度样本、基质干扰、多 ...

Using MALDI-TOF, researchers can quickly and accurately determine polymer, protein and nucleic acid masses. They can also analyze and resolve complex assortments of smaller peptides and ...

What is time-of-flight mass spectrometry? How ToF MS has gained more interest since the commercialization of MALDI. Why a high-speed ADC is key to ToF MS performance. Mixed-signal front end that ...
