MALDI-TOF Analysis at Biolytix AG – Rapid microbial identification method with ISO 17025 accreditation –
Microbiological diagnostics have undergone enormous technological advances in recent years. One of the most significant innovations is MALDI-TOF analysis.
What is MALDI-TOF MS?
MALDI-TOF stands for Matrix-Assisted Laser Desorption/Ionization – Time of Flight.
- MALDI: The sample is mixed with a “matrix” and ionized by a laser (converted into charged particles).
- TOF (Time of Flight): These ions travel through a measuring device at different speeds depending on their mass. Using mass spectrometry (MS), their mass can then be determined.
How is this analytical method used?
The MALDI-TOF method is used in our laboratory for the rapid and reliable identification of bacteria, yeasts, and molds.
A characteristic protein pattern is generated from a pure cultured bacterial, yeast, or fungal culture and compared with a reference database of mass spectra. This database is highly comprehensive and contains spectra of all known pathogenic microorganisms as well as relevant microorganisms from food, nature and the environment, industry, research, and science.
Under suitable sample conditions, a microorganism can be identified within a very short time.
The advantages
-
High Speed – Results significantly faster than with conventional microbiological methods
- Precise Microbial Identification – Identification down to species or even subspecies level through spectral comparison with the world’s largest microbial identification database
-
Cost-Effective Alternative – Economical alternative to complex conventional biochemical tests
-
Wide Range of Applications – Suitable for water, food, cleanroom, and environmental samples
- Accredited Quality – Legally compliant and standardized results through accredited testing procedures
What does it mean that the method is performed within the accredited scope?
Performing MALDI-TOF analysis within the ISO 17025 accredited scope means:
- validated and standardized testing procedures
- documented quality assurance
- traceability and standards-compliant processes
- legally reliable results for authorities, audits, and certifications
