PiColorLock™ Phosphate Detection Reagent Summary
| Description |
PiColorLock phosphate detection reagent changes colour in the presence of inorganic phosphate (Pi). This can be exploited to measure any enzyme that generates Pi including ATPases, GTPases, phosphatases, heat-shock proteins and DNA unwinding proteins. The unique formulation of PiColorLock affords enhanced assay linearity, dynamic range and colour stability; it is also possible with PiColorLock to work with unstable substrates (e.g. ATP, GTP) that give high non-enzymatic background signals with other acidic dye-based detection reagents. | Features | Benefits | | Colorimetric assay | Simple, scalable and non-radioactive | | Compatible with almost any assay buffer | Flexibility over a wide range of existing assays | | Stable reagent formulation | Long shelf life | | Unique accelerator and stabilizer | Speeds up color development | | PiColorLock-Pi complex is very stable | No precipitation, results can be measured over several hours - ideal for HTS | | Wide linear range | No inhibition of color development by high concentrations of protein |

![PiColorLock Gold Colorimetric Assay Kit [303-0125] - Most detection reagents form very unstable dye complexes and samples need to be read promptly. In cuvette assays there can be a total loss of signal if a precipitate forms and settles. In plate assays, the data become extremely erratic when clumps of material form in the light path. PiColorlock complexes are stable for many hours, which allows multiple assay plates or cuvettes to be conveniently set up as a batch and read later using plate stackers or other automated equipment.](http://images.novusbio.com/fullsize/PiColorLock-Gold-Colorimetric-Assay-Kit-303-0125-img0004.jpg "PiColorLock Gold Colorimetric Assay Kit [303-0125] - Most detection reagents form very unstable dye complexes and samples need to be read promptly.
