Evaluation of three sample preparation methods for the identification of clinical strains by using two MALDI‐TOF MS systems

Journal of Mass Spectrometry, 2021
Matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOF MS) has revolutionized the microbial identification, especially in the clinical microbiology laboratories. However, although numerous studies on the identification of

MALDI-TOF MS analysis of urinary nucleosides [PDF]

Journal of the American Society for Mass Spectrometry, 2005
As RNA turnover seems to be impaired in cancer patients, modified nucleosides have been evaluated as potential tumor markers. Modified nucleosides are mainly formed post-transcriptionally in tRNA, set free during RNA metabolism, and excreted in urine.

Direct Rapid Identification from Positive Blood Cultures by MALDI-TOF MS: Specific Focus on Turnaround Times

Microbiology spectrum, 2021
Using MALDI-TOF MS directly from blood culture bottles reduces the time required for pathogen identification, and the turnaround times for final identification have been compared with overnight incubation from solid media in previous studies.

Immuno-MALDI-TOF-MS in the Clinic [PDF]

Clinical Chemistry, 2018
There is an ever-increasing need for robust and cost-effective methods that allow researchers and clinicians to detect molecular signatures of disease from patient samples, such as biofluids or biopsies. Traditional methods for measuring protein concentrations often lack specificity, precision, throughput, or robustness.

Optimized MALDI-TOF MS Strategy for Characterizing Polymers [PDF]

Frontiers in Chemistry, 2021
In recent years, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) plays an essential role in the analysis of polymers. To acquire a more reliable strategy for polymer profiling, we characterized four representative polymers including polyethylene glycol 6000, polyvinylpyrrolidone K12, polymer polyol KPOP-5040,
