The production of large quantities of the lymphokine(s) histamine-releasing activity (HRA) and its partial purification by Sephadex G-75 and ion-exchange chromatography on carboxymethyl (CM) Sepharose 6B have been detailed (M. A. Lett-Brown, D. O. Thueson, D. E. Plank, M. P. Langford, and J. A. Grant, Cell. Immunol. 87, 434-444, 1984). Two peaks of activity (HRA I and II) were recovered. Preparations of HRA have now been analyzed by high-performance liquid chromatography (HPLC). Thoracic duct lymphocytes stimulated with 200 U/ml streptokinase were used as a source of HRA. Gel-filtration HPLC on a TSK 3000 column separated HRA into two peaks of activity (10,000-20,000 and 1300 Da). Reverse-phase high-performance liquid chromatography using a Nucleosil C-8 column showed that HRA II (the activity eluted at a conductivity of 18-20 mmho on the CM-Sepharose column) eluted as a single sharp peak, the main protein contaminant being cytochrome c, the carrier protein added to enhance the yield of HRA. High-performance liquid chromatography was found to be a useful analytical tool and may be suitable for the large-scale purification of HRA.
