Colorimetric assay kit
$536.00 - $4,191.00
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. Na+/K+-ATPase activity determination (PMID: 21304972) 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 Phosphate Detection Systems can also be purchased for developing simple assays for any phosphate-generating enzyme. This non radioactive colorimetric assay kit uses a 96 well format, and all the necessary reagents are supplied for measuring enzyme activity and are ideal for high throughput drug screening.
