Fish authentication by MALDI-TOF mass spectrometry.
Recent EU directives and regulations for quality control and authentication of food products have prompted the development of new methods for large-scale tests to ensure the protection of consumers. In view of this, an innovative method based on MALDI-TOF mass spectrometry has been developed and successfully applied to fish authentication. Highly specific mass spectrometric profiles from 25 dif...
متن کاملRoutine identification of Nocardia species by MALDI-TOF mass spectrometry.
We here show adequate species identification for bacterial isolates of the genus Nocardia spp. through VITEK mass spectrometry. Application of a specific sample preparation method in combination with a robust matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) database leads to 94% accurate identification to the species level on a set of 164 isolates. The...
متن کاملAnalysis of RNA cleavage by MALDI-TOF mass spectrometry
A method of analysis is presented that utilizes matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) to monitor the kinetics and products of RNA cleavage, by use of a program designed to mass-match observed MS peaks with predicted RNA cleavage products. The method is illustrated through application to the study of targeted oxidation of RNA stem loops from ...
متن کاملIdentification of fungal microorganisms by MALDI-TOF mass spectrometry.
Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has emerged as a reliable tool for fast identification and classification of microorganisms. In this regard, it represents a strong challenge to microscopic and molecular biology methods. Nowadays, commercial MALDI systems are accessible for biological research work as well as for diagnostic applications...
