Abstract
Kallikrein is prepared by the fractional precipitation of pigs' urine with acetone, collecting the kallikrein-containing precipitate and dissolving it in water, subjecting the solution obtained to a further acetone precipitation, dissolving the precipitate obtained in water and subjecting the aqueous solution obtained to chromatography on a polydextrane column to obtain a colourless, aqueous solution of kallikrein containing less than 10 m g of protein per KU.
