Naphthol AS-D Chloroacetate Esterase (AS–DCE) Stain
Intended Use:
This kit is for staining bone marrow cell and bloodcell smear.
Principle:
Naphthol AS-D chloroacetate can be hydrolyzed into Naphthol AS-D by Esterase to mix with diazonium salt and form insoluble red-brown precipitate in cytoplasm. Positive reaction is only found in granulocytes; hence, it is also called "Specific Esterase Stain".
