Bruker Daltonik GmbH and the German Collection of Microorganisms and Cell Cultures (DSMZ) have announced collaboration for the identification and classification of microorganisms from peptide and protein profiles measured by MALDI-TOF mass spectrometry.
The DSMZ uses Bruker Daltonik's CLINPROT BioTyper™ system to generate protein profiles and to perform the required advanced data analysis.
The DSMZ is the German National Resource Centre for Biological Material, and currently stores and maintains approximately 14,000 cultures, representing 6,900 species from different types of microorganisms, including archaea, bacteria, yeasts and fungi.
In the course of the planned collaboration, a comprehensive database will be generated that will include species and strains for many different application areas such as microbiological classification, clinical and diagnostic infectious disease research, as well as environmental analysis, food safety and water quality.
The DSMZ will use the CLINPROT BioTyper for its internal quality control of strains, as well as for its on-going phylogenetic research in various microorganisms.
The DSMZ adopted the CLINPROT BioTyper technology for microorganism characterization due to the ability of MALDI-TOF mass spectrometry to identify large numbers of samples originating from complex mixtures of microorganisms, unequivocally and without the need for expert training.
The CLINPROT BioTyper system includes an bench-top MALDI-TOF with a small footprint that is well suited for operation in biological laboratories that are not mass spectrometry core facilities.
Prof. Dr. Erko Stackebrandt, Managing Director of DSMZ, pointed out, "There was an urgent need for a next- generation technique for the fast, convenient and cost-effective identification of microbial strains."
"Bruker Daltonik's CLINPROT BioTyper is well suited for this purpose, as it fulfills these requirements. It has proven to be very robust and reproducible."
Dr. Wolfgang Pusch, Director of Clinical Proteomics and Biomarker Analysis, commented, "We are very pleased to have the DSMZ with their extraordinary expertise in microbiology as a strategic partner."
"This cooperation is a major step towards our goal of not only applying mass spectrometry in expert core facilities, but also making it available as a robust tool in routine biological analysis."
"The dual capabilities of our ClinProt MALDI-TOF systems for microorganism identification, as well as for tissue and body-fluid protein biomarker discovery, should be attractive for many clinical diagnostics research laboratories."
The CLINPROT BioTyper system will be introduced internationally at the Bruker Daltonics Pittcon booth #3155 in Orlando, Florida on March 13-16, 2006.
