2. FIG. 1
BIAcore overlaid sensorgrams showing the binding of Dac g 4 on RAMFcγ-presented mAbs. After injection of mAbs (A to H, 50 μg/ml in HBS-P20), immobilization level of mAbs was considered as the baseline. a, Injection of Dac g 4 (10 μg/ml in HBS-P20); b, HBS-P20 injection; c, regeneration of the flow cell. RU, Resonance units.

5. FIG. 3
Double-site immunoassay of Dac g 4 with mAb H as capture antibody and biotinylated mAb A. Group 4 allergens from four grass pollens (D. glomerata, Festuca elatior, Lolium perenne, and Phleum pratense) were compared with Dac g 4-IP. Results were expressed as percentage of maximal absorbance.

6. FIG. 4
Inhibitory capacities of 11 grass pollen SEs compared with Dac g SE (100%). Relative contents of cross-reactive allergens were calculated from the protein concentration needed for 50% inhibition. Values are means of triplicate determinations. Normal human sera demonstrated no anti-Dac g 4 IgE-binding activity.
