mCyp c 1–specific rabbit antiserum inhibits rCyp c 1–induced basophil degranulation in vitro and Cyp c 1–induced allergic symptoms in vivo. A, Rat basophil leukemia cells were loaded with pooled sera from rCyp c 1–sensitized mice in the presence or absence of mCyp c 1–specific rabbit antiserum or control antiserum (x-axis). The percentage of total β-hexosaminidase release is displayed on the y-axis (triplicates ± SD). B, Significant (**P < .01) suppression of allergic symptoms in Cyp c 1–sensitized mice by mCyp c 1–specific rabbit antiserum after challenge with Cyp c 1. Allergic symptoms (y-axis: mean symptom scores ± SD) in Cyp c 1–sensitized mice having received mCyp c 1–specific or control antiserum (x-axis).
