Profilin has been purified from bovine thyroid by a new and simple method, employing affinity chromatography on DNase I-agarose and gel filtration. This procedure should be particularly useful for purifying profilin from tissues in which it is present in relatively low concentration because it does

β¦ Synopsis
Acetylcholinesterase from electric eel is selectively immobilized on Amberlite IR-120 resin equilibrated with Al 3+ ions. Immobilized acetylcholinesterase activity is stable at least for 85 days in the wet state at 10Β°C and for 180 days in the dry state at room temperature. Activity determinations in the presence of eserine sulfate, decamethonium bromide, quinidine sulfate and butyryl thiocholine iodide suggested that the immobilized enzyme exhibited essentially the same properties as did the free enzyme.
