Enzyme3
A combined cytochemical and biochemical analysis of non-specific esterases in differentiating root tissues of the broad bean showed that maximal enzyme activity, expressed on a per segment, per unit protein or per unit area of average-sized section basis, occurred within the zone of cell expansion, elongation and differentiation of procambial tissues.

In a study of non-specific esterases in soft fruit ripening and senescence, cytochemical studies demonstrated that enzyme activity was associated with subcellular structures in the pulp cells of the ripening strawberry. (gre.ac.uk)
Enzyme activities are expressed Inhibitors,Modulators,Libraries as nmole of naphthol or B naphthol min mg protein. (srcinhibitors.com)

Distribution of T-lymphocytes in follicular lymphomas as revealed by acid alpha-naphthol acetate esterase. (bmj.com)
Twelve cases of follicular centroblastic/centrocytic malignant lymphoma were studied for acid non-specific esterase. (bmj.com)
Activity4
Three study locations (Djougou, Gogounou and Kandi) showed high oxidase activity and four sites (Djougou, Ouake, Copargo and Kandi) showed elevated esterase activity. (biomedcentral.com)
Using the histochemical reagents, naphthol AS D acetate and the diazonium salt, fast red violet LB salt, a biochemical study of non-specific esterases extracted from broad bean root tips, has shown that these enzymes have an estimated Km of 0.07 mM, a pH optimum of 5.5 and that they lose substantial activity when dialysed against distilled water as opposed to 5mM magnesium chloride and 10mM phosphate buffer. (gre.ac.uk)
Although esterase activity changed little during the transition from 'maturing 1 to 'mature 1 when expressed on either basis, the specific activity of the enzymes fell markedly. (gre.ac.uk)
The activity against each substrate was calculated from standard curves of absorbance for known concentrations of naphthol or B naphthol. (srcinhibitors.com)
Total1
1961). Among workers engaged in the production, handling and shipping of carbaryl, those most heavily exposed (air concentrations of 0.23 to 31 mg/M 3 ) excreted large amounts of total 1-naphthol (Best & Murray, 1962). (inchem.org)
Cells1
Statistical analyses of histochemical data have shown that particles staining for naphthol AS BI phosphatase in dividing unfixed root cells of Vicia f aba do not act as a 'trigger 1 in the way suggested for animal cells, since there were significantly greater numbers of particles in mitotic cells as opposed to interphase cells in all 3 root tissues, apical initials, procortex and central cylinder.

Acetate Esterase2
Histological staining techniques have revolutionized our understanding of cellular processes, and the α-Naphthyl Acetate Esterase (α-NAE) stain holds a significant place in this field. (pscientifics.com)
The α-Naphthyl Acetate Esterase (α-NAE) stain offers a fascinating glimpse into cellular esterase activity. (pscientifics.com)
Chloroacetate esterase1
In the blast cells of all ALL cases myeloperoxi- dase, Sudan Black B and naphtol ASD chloroacetate esterase are claimed to be negative (Shaw, 1976). (swirlzcupcakes.com)

We also assessed the sublethal effects of Proclaim Fit ® on the specific activity of some well-known detoxifying enzymes including α-esterase, β-esterase, and Glutathione S-transferase (GST) in the honey bees. (researchsquare.com)
Enzyme assays revealed the considerable involvement of the enzymes, especially GST and α-esterase, in detoxification of the Proclaim Fit ® , but their activities were significantly influenced by route of exposure and age of bee. (researchsquare.com)
Esterases (ESTs) are the enzymes involved in Phase I xenobiotic detoxification reactions that degrade toxins via hydrolysis (Xu et al. (researchsquare.com)
2013). These hydrolytic enzymes are divided into alpha (α) and beta (β) esterases depending on their ability to hydrolyze the substrates alpha- and beta-naphthyl, respectively (Dahan-Moss and Koekemoer 2016). (researchsquare.com)
Stain1
This technique is referred to as "Non-specific Esterase Stain" due to its lack of specificity toward esterases. (pscientifics.com)
