A radioimmunoassay was employed in order to quantitate IgE on the basophil surface in 6 normal and 10 pollen sensitive subjects. A basophil-rich fraction obtained from whole blood in a Ficoll gradient was incubated with specific anti-IgE; the inhibition produced by surface IgE was standard inhibition curve. Atopic patients had on the average about 10-30 times as many IgE molecules per basophil as control subjects. Total and specific IgE as well as degranulation by Lollium perenne crude extract were also studied in both populations and their results compared with those of basophil IgE quantitation.
