[Prostaglandin-H-synthase: stability and activity during immobilization on silica gel].

Prostaglandin H synthase was isolated in the form of microsomes from sheep vesicular glands and immobilized on silica gel. This system of prostaglandin synthesis was activated by calcium ions and stabilized by adrenaline. Microsomes immobilized in the presence of adrenaline and calcium ions were stable upon storage at 4 degrees C.
