应用

2-Naphthyl acetate has been used as a substrate:

in substrate sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) to examine the composition of lipases in larvae and adult specimens
in the preparation of zymograms to identify proteins with lipase activity
to measure non-specific esterase activity and β-esterase enzyme activity

生化/生理作用

2-Naphthyl acetate/β-naphthyl acetate (BNA) is an ester substrate. It can be used in staining gels to detect esterase activity. BNA dissolved in acetone and ethanol produces a dark and very light/no background respectively. Hence destaining is not necessary if ethanol is used to dissolve BNA for esterase staining of gels.
