title: A simple, large scale process for purifying human urinary kallikrein, based on reverse osmosis and ammonium sulfate precipitation.
abstract: A simple, large scale process for the purification of human urinary kallikrein is described which is based upon concentration by reverse osmosis, ammonium sulfate precipitation, and gel filtration on a column of Sephadex-G-150. The yield in protein is higher than any reported in the literature to this date; the purified enzyme seems to be identical to that reported by Figueiredo and Mares-Guia at the Kinin-Symposium in Paris, 1978, based on the procedure of Hial, et al., (1974).
