抗原决定基

这说明了屋尘螨、花粉、和霉菌等变应原可能含有共同的抗原决定基，即不同种变应原间可能存在共同抗原，都能与体内致敏变应原的特异性抗体相结合，发生了交叉反应。

These explain house dust mite , pollen and fungus contain common epitope or common antigen existing in different allergen . All the allergen mentioned above can combine specific antibody and conduct cross-reaction .

为了检测在寒冷条件下，水稻ICE同系物是否通过调节水稻DREB的同系物来对冷胁迫的作出反应，我们鉴定了一个含有ICE特异基序多肽抗原决定基。

To examine whether rice ICE homologs function in cold acclimation via regulation of rice DREB homologs in response to cold stress , we assessed a polypeptide epitope containing an ICE-specific motif .

抗独特型抗体（Ab2）是指针对独特型抗体（Ab1）的独特型抗原决定基产生的抗体。

Antibody idiotype is the antigen determinant of antibody .

但要确定共同抗原决定基的序列和具体靶位点还需要应用免疫印迹、westernblot和ELISA抑制试验等方法来探讨交叉抗原性及其程度。

However , immunoblotting , Western blot and ELISA inhibition test are still needed to explore mechanism and degree of cross-reacting antigen to confirm the sequence of common epitope and specific target site .
