Polymorphism and immunochemical cross-reactivity of acetylcholinesterases from the brains of human, dog, hog, bovine and horse.
In the caudate nucleus of the species tested about 20% of the acetylcholinesterase was salt soluble and sedimented in sucrose density gradient centrifugation as monomeric 5 S and tetrameric 10 S enzyme. About 80% was solubilized by micellar concentrations of Triton X-100 and sedimented as a tetrameric 10 S species in the presence of detergent but formed aggregates in the absence thereof. All the enzyme displayed poor cross-reactivity with a precipitating assay (Ouchterlony) but in a solid phase non-precipitating assay the cross-reactivity could be quantified and ranged from 96 to less than 1% depending on the species.
