ActivX™ TAMRA-FP Serine Hydrolase Probe

The TAMRA-FP probe feature a reactive fluorophosphonate group that is used to label and detect active serine hydrolases by fluorescent gel imaging, capillary electrophoresis or mass spectrometry. An anti-TAMRA antibody is also available for immuno-enrichment of TAMRA-FP probe-labeled proteins.

ActivX™ active-site enrichment probes are advantageous for determining active enzyme levels through the use of analog-tagged probes to allow profiling of both inactive and active enzymes. The ActivX probes selectively enrich only those enzymes that are functionally active and biologically relevant at the time of labeling. With selective enrichment, one can identify and profile target enzyme classes across samples or can assess the specificity and affinity of enzyme inhibitors.

The serine hydrolase superfamily is one of the largest, most diverse enzyme families in eukaryotic proteomes. Serine hydrolases are generally grouped into two large families: serine proteases (e.g., trypsin, elastase and thrombin) and metabolic serine hydrolases. Metabolic serine hydrolases are divided into multiple enzyme subclasses (e.g., esterases, lipases, amidases and peptidases) based on structure, catalytic mechanism and substrate preference. These probes can be used to assess activity or screen small molecule inhibitors against enzymes derived from cell lysates, subcellular fractions, tissues and recombinant proteins.
