Profiling PDEs with the Transcreener AMP²/GMP² Phosphodiesterase Assay
About the Transcreener AMP2/GMP2 PDE Assay Kit
Detect any AMP/GMP producing enzyme (e.g., ligases, synthetases, phosphodiesterases) using any precursor substrate, including cAMP, cGMP, ATP, or NAD. It is the only activity assay method for direct detection of unlabeled AMP or GMP; i.e. without using coupling enzymes. The method is simple and HTS-proven: run your enzyme reaction, add detection reagents, and read the far red FP or TR-FRET signal on any multimode plate reader.
XMP enzyme products, including AMP, GMP and CMP displace a fluorescent tracer from a highly selective antibody resulting in a change in fluorescence. Both assays use a far red tracer, which reduces compound interference and provides a robust ratiometric readout. Make measuring cyclic nucleotide phosphodiesterase activity easy with a simple, proven, HTS-ready assay.
