Co-crystallization of hAChE with Ligands

Check if the same lab product or an alternative is used in the 5 most similar protocols
Ligands, donepezil, 9-aminoacridine and BW284c51 were obtained from Sigma-Aldrich and 30–60 mM stock solutions were
prepared in DMSO. In preparation for co-crystallization, samples of hAChE were dialyzed in 10 mM NaCl, 10 mM HEPES, pH 7, and
concentrated to 6–10 mg/mL. About 1 h prior to crystallization, the solution of hAChE was combined with stock solutions of
ligands in a molar ratio of 1:5 or 1:10 to obtain binary complexes. Co-crystals were grown by vapor diffusion at 10 °C in
sitting drop microbridges or 9-well glass plates (Hampton Research, Aliso Viejo, CA). Well solutions containing 10 mM sodium
citrate, 100 mM HEPES, pH 7.5, 7–12% PEG6000 were used in crystallization experiments with donepezil and BW284c51 and 200
mM potassium nitrate, 100 mM HEPES pH 7.5, 9% PEG 3350 were used to produce crystals with 9-aminoacridine. Crystals typically
appeared within 2-4 weeks (~0.1-0.2 mm in the longest dimension) and over 2-4 months, depending on the ligand, slowly grew
to full size (> 1 mm). Largest crystals were observed in drops that contained 1-3 crystals.

Five characterized histidine-dependent strains of Salmonella typhimurium (TA98, TA100, TA102, TA1535, TA1537; MFDS, Osong, Korea) were utilized for bacterial reverse mutation assay (Ames test) in accordance with OECD guideline 471 [27 ]. S. typhimurium strains were incubated with the AA extract with or without an S9 mix in the dark at 37℃ for 48 h. The standard mutagens (2-nitrofluorene, sodium azide, mitomycin C, 9-aminoacridine, and 2-aminoanthracene; Sigma-Aldrich, St. Louis, MO, USA) were used as positive controls. The extract was considered to be positive if there was a two-fold increase relative to negative control or a dose-dependent increase in the number of revertant colonies.

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.
