transfer of ova-hypersensitivity by the cell line ( 1 ) was ige-dependent and did not occur when the cells were pre-exposed to antiserum containing ova-specific igg alone , ( 2 ) was blockable by saturation of cell surface receptors in the recipient with myeloma ige ( but not myeloma igg ) , and ( 3 ) did not occur in mast cell-deficient mice carrying the w/wv mutation , in contrast to their normal heterozygous littermates which developed marked ova-hypersensitivity at the injection site .
