Molarity Calculator

Naphthol AS-TR Phosphate disodium is a water-soluble dye commonly used as an enzymatic substrate in various biochemical assays to detect alkaline phosphatase activity. Naphthol AS-TR Phosphate disodium has unique chemical properties that allow it to be hydrolyzed by alkaline phosphatase, forming a colored product that can be detected spectrophotometrically. This makes it a useful tool for monitoring enzyme activity in biological samples such as serum or urine.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
