PBlue Phosphate Assay Kit

Our PBlue Phosphate Assay 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 – 660 nm) 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.
Our Cell-Based Assay Kits address the pharmaceutical and biotechnology customers’ ever-growing needs driven by the deluge of drug targets derived from genomics and proteomics. Our customers are seeking to perform large scale screens in cell-based systems because of the accurate and whole cell data which are promising and representative of the organism’s physiological condition. The kit comes with a complete system of all reagents for the assay and an easy-to-follow protocol.
