Organ cultured rat diaphragm segments were used to assay a factor which increases endplate-specific acetylcholinesterase. This factor can be substantially purified by vacuum distilling it at 37°C into a dry-ice-acetone cold trap. Sources from which the factor can be distilled include eel electric organ homogenate, rat diaphragm homogenate, and medium conditioned with neurally stimulated muscle.
