There was a good correlation with esterase staining and AChR labeling in the normal dog. (journals.plos.org)
Serial sections were evaluated with light microscopy (esterase reaction) and fluorescent microscopy (red fluorescence) and localization of stainings compared. (journals.plos.org)
Multifocal areas of esterase reactivity were identified, but it could not be determined from this reaction if staining correlated with localization of motor end - plates. (journals.plos.org)
