Abcam, ab270004, Phosphate Assay Kit - PiColorLockTM

Size: 600Test / 2500Test
Phosphate Assay Kit ab270004 quantifies inorganic phosphate (Pi), with a colorimetric readout (max 635nm, range 590-660nm). The PiColorLock™ reagent at the core of the assay, changes colour in the presence of inorganic phosphate (Pi).
Product details:
Phosphate Assay Kit - PiColorLock™ (ab270004) 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 Phosphate Assay Kit - PiColorLock™ (ab270004) affords enhanced assay linearity, dynamic range and colour stability; it is also possible to work with unstable substrates (e.g. ATP, GTP) that give high nonenzymatic background signals with other acidic dye-based detection reagents.
Key benefits:
Colorimetric assay – Simple, scalable and nonradioactive
Compatible with almost any assay buffer – Flexibility over a wide range of existing assays
Stable reagent formulation – Long shelf life
Unique accelerator – Speeds up color development
Unique stabilizer – Suppresses nonenzymatic backgrounds with acid labile substrates (ATP or GTP)
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
The unique PiColorLock™ Stabilizer prevents background drift with time.
General Notes
This product is manufactured by Expedeon, an Abcam company. It was previously called PiColorLock. Expedeon product code 303-0030 is the same as the 600 test size of this product and code 303-0125 is the same as the 2500 test size.
