Acetylthiocholine iodide

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Inhibitors and Substrates-Acetylthiocholine iodide, 5,5′-dithiobis(2-nitrobenzoic acid) (Ellman's reagent), dithiothreitol, tacrine (9-amino-1,2,3,4-tetrahydroacridine hydrochloride hydrate), BW284c51, decamethonium, and edrophonium were purchased from Sigma. m-(N,N,N-trimethylammonio)trifluoromethylacetophenone (TFK+) and (−)huperzine A were purchased from Calbiochem. Acrylodan was obtained from Molecular Probes (Eugene, Oreg.). Fasciculin 2 (purified from the venom of Dendroaspis angusticeps) was a gift of Dr. Pascale Marchot (University of Marseille, France). Drs. Yacov Ashani and Bhupendra P. Doctor (Walter Reed Army Research Center, Washington, D.C.) kindly provided 7-((methylethoxy) phosphinyl)-oxyl)-1-methylquinolinium iodide (MEPQ) and procainamide-linked Sepharose CL-4B resin. m-tert-Butyl trifluoromethylacetophenone (TFK+) was synthesized as described (21) and kindly provided by Dr. Daniel Quinn, University of Iowa, Iowa City, Iowa. All other chemicals were of the highest grade commercially available.

実験手順: Sodium silicate solution (˜14% NaOH, ˜27% SiO2), tetraethylorthosilicate (TEOS, 98%), Dowex 50WX8-100 ion-exchange resin, acetylcholinesterase (AChE, from electrophorus electricus, EC 3.1.1.7), paraoxon, aflatoxin B1 (AfB1, from aspergillus flavus), 5,5′-dithiobis-(2-nitrobenzoic acid) (DTNB), carboxymethylcellulose sodium salt (CMC), and Triton X-100 were obtained from Sigma-Aldrich. Anhydrous glycerol and acetylthiocholine iodide (ATCh) were purchased from Fluka BioChemika Ultra (UK). Diglyceryl silane (DGS) was synthesized in our lab using by transesterification of TEOS with anhydrous glycerol as described in detail elsewhere.26 Polyvinylamine (PVAm; 1.5 MDa) was obtained from BASF (Mississauga, Canada), as a gift. Mead brand cardboard paper substrate with a white hydrophobic clay coating (Manufactured by Hilroy, Toronto, Canada) was purchased from McMaster University Bookstore. Distilled deionized water (ddH2O) was obtained from a Milli-Q Synthesis A10 water purification system. All other reagents were of analytical grade. Distilled was obtained from a Milli-Q Synthesis A10 water purification system
