[Comparative iodination of a series of allergens]

The study of 27 allergens, carried out with the use of the standard technique of chloramine iodination by Hunter's method, revealed that the biological properties of the allergens were not essentially related to their capacity for binding 125I, this capacity being, on the whole, low. The blood sera of patients with allergic diseases were found to be no different from the blood sera of healthy persons in their capacity for binding 125I.
