Check if the same lab product or an alternative is used in the 5 most similar protocols
The acetylcholinesterase inhibition assay was performed based on the modified methodology of Ellman et al. (1961) [39 (link),40 (link)]. Briefly, 50 μL of 0.25 U/mL enzyme in phosphate buffer (PBS) (8 mM K2HPO4 (Vetec, Recife, Brazil), 2.3 mM NaH2PO4 (Synth, Diadema, Brazil), and 0.15 M NaCl (Vetec, Recife, Brazil), pH 7.5), 50 μL of PBS buffer, and 50 μL of EE in different concentrations (solubilized in 15% methanol, Vetec, Recife, Brazil) were added to the 96-well microplates. This mixture was incubated for 30 min at 37 °C. Then, 100 μL of substrate were solubilized in distilled water q.s.p. 20 mL (0.24 mM acetylthiocholine iodide 0.04 M, Na2HPO4 and 0.2 mM DTNB, all purchased from Sigma-Aldrich, Jurubatuba, Brazil) and added to the 96-well plate. The mixture was again incubated for 10 min at 37 °C. Subsequently, the absorbance reading of each triplicate was performed at 405 nm using a Multimode Plate Reader (EnSpire, Perkin-Elmer, Singapore). Inhibitory activity was calculated as a percentage. Galantamine hydrobromide was used as a positive control (0.01–2.0 μg/mL).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
