Transcreener® ADP² FI Assay

The Transcreener® ADP² Fluorescent Intensity (FI) Assay from BellBrook Labs extends the Transcreener® platform for ADP detection by utilizing a simple fluorescent intensity output which can be used on both fluorescence readers typically found in academic and therapeutic research labs (such as the FLUOstar Omega and POLARstar Omega) as well as more complex multimode plate readers more commonly used in core facilities and HTS labs (such as the PHERAstar Plus and PHERAstar FS).

The Transcreener® ADP² FI Assay is a red, competitive fluorescence intensity assay based on the detection of ADP and therefore is compatible with any enzyme class that produces ADP, including protein, lipid, and carbohydrate kinases, ATPases, DNA helicases, carboxylases and glutamine synthetase. It is a simple one step homogenous detection assay, and is flexible with regard to ATP concentration (0.1 to 1,000 µM ATP). The assay provides excellent signal at low substrate conversion, with a Z' ≥ 0.7 at 2.5% ATP conversion using 1 µM ATP.

Transcreener is the simplest, most direct ADP detection method available: binding of ADP to antibody displaces a tracer, causing a change in its fluorescence properties. It has fewer reagents, fewer assay steps and less chance of inter­ference compared with other methods, all of which rely on coupling and/or reporter enzymes
