title: Slow-reacting substance of anaphylaxis:  studies on purification and characterisation.
abstract: We have demonstrated the role of arachidonic acid and lipoxygenase in the genesis of SRS-A and the possible role of lipoxygenases in its metabolism. SRS-A has been purified in microgram quantities together with closely related material. We have identified 5,12 di-hydroxy-6, 8, 10, 14 eicosatetranenoic acid released by antigen challenge, and which we feel is related to SRS-A. Further structural work is in progress.
