NAPHTHOL AS-BI PHOSPHATE Usage And Synthesis

Chemical Properties

Light yellow crystalline powder

Uses

Naphthol AS-BI phosphate is suitable to use:

• in tartrate-resistant acid phosphatase (TRAP) staining to detect osteoclast activity
• as a component in Tris-HCl in staining cells to measure alkaline phosphatase (ALP) activity
• to perform alkaline phosphatase reaction

', 'Substrate for the histochemical demonstration of acid and alkaline phosphatase. Substrate for the fluorometric assay of acid and alkaline phosphatases. Demonstration of acid phosphatase in paraffin embedded tissue. Cytofluorometric assay of acid phosphatase in single living cells.

Biological Activity

Naphthol AS-BI can be used as a substrate to determine alkaline and acid phosphatase. It is also used to determine the activity of acid phosphatase in single cells.
