FIG. 6 Autoradiograph of IgE inhibition experiments performed with SF and CA extracts, respectively. Serum pool A, pool B, and pool C were preincubated with 0 μg and 300 μg of CA extract (SF; lanes 1, 2, 4, 5, 7, 8), and 80 μg of SF extract (SF; lanes 3, 6, 9). Nitrocellulose-blotted sunflower honey proteins were incubated with this solution, and immunoblotting was performed. Serum pool B was preincubated with 0 μg, 40 μg, and 80 μg of SF extract (CA; lanes 1 to 3) and 300 μg of CA extract (CA; lane 4). Thereafter nitrocellulose-blotted honeybee head proteins were incubated with this solution, and immunoblotting was performed. Serum pool X was preincubated with 0 μg, 5 μg, 25 μg, and 125 μg of SF extract (BV; lanes 1 through 4) and 100 μg of BV extract (BV; lane 5). Nitrocellulose-blotted honeybee sac proteins were incubated with this solution, and immunoblotting was performed. Lane B, buffer control.
