Cyclic Nucleotide Phosphodiesterase assay Kit

Cat.No.: Kit-0667
Product Overview: Unique, non-radioactive, colorimetric assay.Used to screen inhibitors and modulators of cyclic nucleotide phosphodiesterase activity.HTS format permitting rapid assays of large numbers of samples.
Size: 96 wells
Description: A BIOMOL GREEN Quantizyme Assay System. The Cyclic Nucleotide Phosphodiesterase (PDE) Assay Kit combines a special dual enzyme system with the BIOMOL GREEN Reagent for phosphate detection to create a unique, non-radioactive, colorimetric assay. This HTS-friendly, mix and read system may be used to screen inhibitors and modulators of cyclic nucleotide phosphodiesterase activity. 96-well microplate format permits rapid assays of large numbers of samples.The basis for the assay is the cleavage of cAMP or cGMP by a cyclic nucleotide phosphodiesterase. The 5"-nucleotide released is further cleaved into the nucleoside and phosphate by the enzyme 5"-nucleotidase. The phosphate released due to enzymatic cleavage is quantified using BIOMOL GREEN reagent in a modified Malachite Green assay. The kit includes Type I cyclic AMP phosphodiesterase (PDE) for validation purposes.
Applications: Colorimetric detection, HTS
Storage: -80°C
