✦ Synopsis

has devised a new procedure for the purification of enzymes, the use of specific antienzymes as precipitants. Thus the urease of the soy bean was precipitated from aqueous extracts of that bean by the addition of highly purified antiurease. Washing the precipitate with 0.4 percent. sodium chloride solution removes the antiurease. The number of urease units per gram of ash-free solids is increased 850 times by this procedure.
