Neutrophilic- Leukocyte Alkaline Phosphatase (NAP) Stain
Intended Use:
This kit is for staining bone marrow cell and bloodcell smear.
Principle:
Neutrophilic-Leukocyte Alkaline Phosphatase stain is based on diazotization-coupling principle. At pH9.2~9.8, Alkaline Phosphatase hydrolyzes Naphthol AS-BI Phosphoric Acid into α-naphthol. The stable diazonium salt and naphthol shall form insoluble colored precipitate in cytoplasm.
