[Histonet] questions regarding to a-Naphthyl Butyrate Esterase stain and a-Naphthyl Acetate stain(non specific esterase)

[weiping Ren]

Hi, Histonetters:
I need to set up non specific esterase staining method on bone marrow smear samples. 
 
My questions are:
1. Are a-Naphthyl Butyrate Esterase stain and a-Naphthyl Acetate stain(non specific esterase) are the same stain?
2. If these are two different stains but have the same clinical diagnosis significance, which one is better regarding to the time and accuracy?
3. Are there any protocols for these stains? Where I can get these references?
 
Thank you!
 
Any suggestions and advice welcome.
