MALDI-TOF MS is a device that generates ions from a sample and then separates the generated ions based on the mass-to-charge ratio in the gas phase MALDI-TOF. Matrix-Assisted Laser Desorption/Ionization Time-Of-Flight. AUTOMATED MASS SPECTROMETRY MICROBIAL IDENTIFICATION SYSTEM. Identification of microorganisms to the species level is the principle objective in microbiology. For many years, such a feat has been accomplished through laborious biochemical assays MALDI mass spectrometry imaging (MALDI-MSI) is the use of matrix-assisted laser desorption ionization as a mass spectrometry imaging technique in which the sample, often a thin tissue section, is moved in two dimensions while the mass spectrum is recorded. Advantages, like measuring the distribution of a large amount of analytes at one time without destroying the sample, make it a useful. MALDI-TOF measures the mass of molecules from a sample that has been embedded in a matrix by using a laser to ablate and desorb the molecules with minimal fragmentation. 1 The sample's molecules are ionized in the resultant hot plume of ablated gases and are funneled into a TOF mass spectrometer that records the ions' mass-to-charge (m/z) ratio. This is achieved by measuring the time the.

Now when a MALDI-TOF analyzes a bacterial sample, a computer can match the resulting map to that of a known species with accuracy equal to that of microbiology's old system. In traditional clinical microbiology, researchers streak a sample onto an agar plate and try to identify microorganisms with several different biochemical tests. Best case scenario, this takes 24 hours, but it takes. MALDI - TOF MS is used in the field of biochemistry to identify the proteins and characterize it because protein contains a molecular weight that has an intact structure that becomes fragmented when ionized. Peptide mass fingerprinting (PMF): Peptide mass fingerprinting is used in the identification of proteins from simple mixture where MALDI - TOF plays an important role by its simple.

Farfour et al. showed that the MALDI-TOF MS Andromas strategy was reliable to identify a set of 659 Gram-positive rods representing 16 bacterial genera and 72 species by the direct colony method . In that report, Andromas MALDI-TOF MS system could not identify Listeria isolates to the species level because of very similar mass spectra Both MALDI-TOF MS systems could accurately identify 98.3% of the isolates at the species level (1359/1383 for Andromas™; 1360/1383 for Bruker Biotyper™) vs. 96.5% for conventional techniques. Furthermore, whereas conventional methods failed to identify rare or emerging species, these were correctly identified by MALDI-TOF MS. Both MALDI-TOF MS systems are accurate and cost-effective. A relevant set of not experimentally infected individuals (control) is required for differential analysis by MALDI-TOF-MS or RP-HPLC in order to discriminate between immune-induced molecules and constitutively present substances (19). This is a prerequisite when no in vitro assays are used to select the bioactive peptides from the immune system of the model invertebrate investigated
