IgE reactivity of dot‐blotted milk samples M1–M10. Aliquots of the sample were dotted in duplicates onto nitrocellulose and incubated with buffer alone, with sera from cow's milk (CM)‐allergic patients 1, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, with sera from subjects who had problems after milk consumption but lacked CM‐specific IgE 23, 24, with serum from a nonallergic control 25, and with sensitized individuals who had CM‐specific IgE without symptoms 2, 26, 27, 28.
