PiColorLock is a phosphate detection reagent for measuring Phosphatases, ATPases and Nucleotidases.
PiColorLock is a phosphate detection reagent for measuring Phosphatases, ATPases and Nucleotidases.
Colorimetric assays for ATPases are invariably based on the formation of colored complexes between an inorganic phosphate and a dye molecule under acidic conditions. Such assays are beset with problems of reagent precipitation and high backgrounds caused by impure substrates (i.e. contaminated with inorganic phosphate) and/or by non-enzymatic (acid) hydrolysis of the substrate.
At the heart of our assay kits is PiColorLock Gold, a superior phosphate detection reagent which ensures high stability of the colored dye-phosphate complexes. Together with specially purified substrates and proprietary stabilizers our kits offer the lowest possible assay backgrounds and outstanding assay performance.
Uniquely, Innova Biosciences ATPase assay kits contain highly purified ATP, which have had any free inorganic phosphate removed – this means the assays have the lowest possible background signal.
PiColorLock reagent may also be purchased separately for developing simple assays for any phosphate-generating enzyme. It is offered in both high (Gold) and standard sensitivity (ALS) formulations to suit almost any assay situation.
