Tissue imaging and profiling by MALDI-TOF MS provides unique information that facilitates understanding of normal biological and pathological processes. SimulTOF Systems technology employing a 5kHz laser and “on-the-fly” peak detection and calibration provides the highest speed and throughput available for tissue imaging. Current research is focused on interrogating protein expression in tissues, directly measuring the distribution of drugs and metabolites in tissues and correlating these distributions with changes in the proteome.
