MALDI-TOF MS Assessment to Identify Environmental Mycobacteria

MALDI-TOF MS in Prenatal Genomics.

Prenatal diagnosis aims either to provide the reassurance to the couples at risk of having an affected child by timely appropriate therapy or to give the parents a chance to decide the fate of the unborn babies with health problems. Invasive prenatal diagnosis (IPD) is accurate, however, carrying a risk of miscarriage. Non-invasive prenatal diagnosis (NIPD) has been developed based on the exist...

Dossier MALDI - TOF ■ Oligonucleotide analysis by MALDI - MS

Matrix-assisted laser desorption (MALDI) time-offlight (TOF) mass spectrometry (MS) has been successfully used for oligonucleotide sequence confirmation by mass analysis of fragments generated by concentration-dependent exonuclease digestion. This approach is particularly well-suited to the analysis of synthetic DNA due to the relatively short length of the DNA strands. Additionally, an importa...

Using MALDI-TOF-MS to test Staphylococcus aureus–infected vitreous

PURPOSE This study aimed to establish a method for testing Staphylococcus aureus in the vitreous of endophthalmitis with matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS), which is simple, fast, and sensitive. METHODS S. aureus at different numbers was either mixed with homogenized vitreous or inoculated in porcine eyes for culturing, followed by homo...

Characterization of fengycin homologues produced by Bacillus subtilis K1 by MALDI-TOF tandem mass spectrometry (MALDI TOF MS/MS)

A Rapid MALDI-TOF MS Identification Database at Genospecies Level for Clinical and Environmental Aeromonas Strains

The genus Aeromonas has undergone a number of taxonomic and nomenclature revisions over the past 20 years, and new (sub)species and biogroups are continuously described. Standard identification methods such as biochemical characterization have deficiencies and do not allow clarification of the taxonomic position. This report describes the development of a matrix-assisted laser desorption/ionisa...
