 Abstract: Three molecular forms of acetylcholinesterase can be isolated by velocity sedimentation from extracts of electric organ from Torpedo marmorata. Their apparent sedimentation coefficients are 6 S, 13 S and 17 S. Characteristic differences are found with regard to their solubilization properties. The 13 S and 17 S forms are extracted only in the presence of high salt concentrations. At low ionic conditions only a fraction of the 6 S form is solubilized. Quantitative recovery of this form can be achieved in the presence of Triton X−100 at concentrations of 0.5−1%. The relative ratio of the various forms changes during the development of the fish
