Bruker has introduced single-use MALDI Biotarget sample plates for the mass spectrometry-based MALDI Biotyper workflow for microbial identification of a wide range of microbial species by means of specific proteomic fingerprints.
The MALDI Biotyper, which allows for microbial identification from pure cultures within a few minutes, enables a broad and unbiased identification of more than 2,000 species of gram-negative and gram-positive bacteria, as well as yeasts.
The MALDI Biotargets complement Bruker’s reusable steel target plates, and can be used in laboratory networks that have a central core facility equipped with a Bruker MALDI-TOF mass spectrometer.
In this use case, the samples can be prepared in satellite microbiology laboratories and can be sent to the central core laboratory for species analysis.
The results can then be reviewed via a local MALDI Biotyper software client for the final approval of the identification by the microbiologist.
Via their barcode-label, the MALDI Biotargets enable sample tracking of the microbial isolates.
The MALDI Biotargets are suitable for the preparation of up to 48 microbial isolates, and MALDI Biotargets are currently for research-use-only.
An additional, proprietary reusable steel BigAnchorChip target plate is the best choice for workflows coming from liquid phase, like in the rapid detection of salmonella after pre-enrichment from stool samples.
