General description
Naphthol AS-BI, also known as 7-Bromo-3-hydroxy-2-naphtho-o-anisidine is a substituted naphthol.
Substrate for the histochemical demonstration of acid and alkaline phosphatase.
Application
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.
Biochem/physiol Actions
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.

Naphthol-ASBI phosphate as a preferred substrate for tartrate-resistant acid phosphatase isoform 5b.
A J Janckila et al.
Journal of bone and mineral research : the official journal of the American Society for Bone and Mineral Research, 16(4), 788-793 (2001-04-24)
Tartrate-resistant acid phosphatase (TRAP) isoform 5b is a potential serum marker for osteoclastic activity. Biochemical assays for serum TRAP activity with para-nitrophenylphosphate (pNPP) have low specificity for bone because of hydrolysis by unrelated nontype 5 TRAPs of blood cells and

Our purpose was to develop a specific immunoassay for tartrate-resistant acid phosphatase (TRACP) 5b using naphthol ASBI phosphate (N-ASBI-P) as a selective substrate for isoform 5b and heparin as a selective inhibitor of isoform 5a. Serum TRACP 5a and 5b

The subcellular localization of acid phosphatase (AcP) in various immunologically-defined neoplastic lymphoid cells including hairy cells was investigated by electron microscopy. 2 substrates, naphthol-AS-BI-phosphoric acid (naphthol-AS-BI-P) and sodium beta-glycerophosphate, were compared. By incubation in naphthol-AS-BI-P containing medium, the reaction product
