We perform microsome incubations for metabolite profiling and metabolite identification. In vivo metabolite profiling could also be performed using biological matrices collected during non clinical or clinical studies (e.g. urine). Full scan and fragmentation of metabolites and parent is performed to assist in structure elucidation. Metabolite identification is performed by interpreting high resolution MS data and low resolution MS/MS fragmentation. Data analysis and metabolite ID data report is prepared upon completion of experiment.
