Phosphatase Assays: liberation of phosphate from peptide, protein or small molecule substrate. Lipase Assays: liberation of phosphate from phospholipids Nucleoside Triphosphatase Assays: liberation of phosphate from nucleoside triphosphates (ATP, GTP, TTP, CTP etc). Quantitation of Phosphate: in phospholipids, proteins and DNAs, etc. Drug Discovery: high-throughput screen for phosphatase inhibitors.

Detection of as little of 20pmoles of phosphate

0.4-50uM

The PBlue Phosphate BioAssay™ Kit is based on a proprietary formulation of the malachite green dye. The PBlue reagent forms a blue colored complex with free orthophosphate. The rapid color formation from the reaction can be conveniently measured on a spectrophotometer (600-660nm) or on a plate reader. The non-radioactive colorimetric assay kits have been optimized to offer superior sensitivity and prolonged shelf life. The assay is simple and fast, involving a single addition step for phosphate determination. Assays can be performed in tubes, cuvettes or multi-well plates. The assays can be conveniently executed in 96-well plates for high throughput screening of enzyme inhibitors.
