Four patients with histories of systemic anaphylaxis or angioedema and urticaria after ingestion of sesame seed or sesame oil-containing products were studied for anti-sesame seed extract IgE by the radioallergosorbent test (RAST). Three of four were found to be positive. RAST inhibition after density-gradient ultracentrifugation of sesame seed extract indicates that the most active allergens appear to have molecular weights between 8,000 to 62,000 daltons.
