Transfer of egg probeins into breast milk

在凝胶过滤中，人类母乳中主要的食物过敏原卵黏液（28 kDa）仅在分子量约为450 kDa的部分被洗脱。其与sIgA的免疫复合物的洗脱曲线与卵泡样液的洗脱曲线几乎相同。类似的结果表明，在母乳中的其他食物过敏原中也观察到食物过敏原与siga的免疫复合物。母乳中存在过敏原与婴儿过敏症状之间的关系，不仅要考虑过敏原的水平，还要考虑过敏原的分子特征。

On gel-filtration, the major food allergen, ovomucoid (28 kDa) in human breast milk was eluted only at the fractions corresponding to a molecular weight of about 450 kDa. Almost same elution profile as that for ovomucoid was obtained for its immune complex with sIgA. Similar results, suggesting the occurrence of food allergens as immune complexes with sIgAs have been also observed for other food allergens in breast milk. Relationship between the presence of allergens in mother's milk and allergic symptoms of their babies should be discussed hereafter in consideration of not only the level but also the molecular feature of allergens.
