title: Bioassay of histamine in the presence of prostaglandins.
abstract: 1. An Amberlite XAD-2 column in a heated (37 degrees C) jacket was incorporated in between two banks of bioassay organs superfused with Krebs bicarbonate solution in cascade. The column removed prostaglandins, E1, E2 and F2alpha and also rabbit aorta contracting substance (RCS) and possibly slow reacting substance of anaphylaxis (SRS-A). 2. The column gave free passage to histamine in concentrations up to 3000 ng/ml. The method described improved the accuracy of histamine bioassay in the.presence of prostaglandins.
