NAPHTHOL AS-BI PHOSPHATE Chemical Properties,Uses,Production
Description
Naphthol AS-BI-phosphate is a fluorogenic substrate for acid and alkaline phosphatases. Naphthol AS-BI-phosphate is cleaved to release the fluorescent moiety naphthol AS-BI (N-ASBI), which can be used to quantify the activity of acid and alkaline phosphatases. Acid and alkaline phosphatases are commonly used for diagnosis of diseases.
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
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.
