Abstract
PURPOSE: To prepare a plasminogen-activating factor, industrially in high yield, by contacting animal-originated cells available in large quantities as concentrated dispersion, with a threonine-containing solution.
CONSTITUTION: Animal-originated cells capable of producing plasminogen-activating factor, e.g. long cells of mouse fetus, kidney cells of African green guenon, factor, etc. are cultured in a medium containing 0.1W0.4 W/V % of threonine at 15W40°C (pref. 25W40°C) and pH5W9 (pref. 6W8), for usually 4W30 days, and the objective plasminogen-activating factor is separated from the medium.
