抗体分子的可变区,不仅能与相应抗原发生特异性结合,而且由于它们都有一定氨基酸序列及空间构型,可起到抗原的作用。这种能诱发异种、同种异体及自身产生相应抗体的决定簇称为抗体的独特型(Idiotype,Id)决定簇。带有Id的抗体称为独特型抗体(Idiotypeantibody,Id或Ab-1)。Id能被带相应抗原受体的另一淋巴细胞识别,进而产生抗独特型抗体(Anti-ldiotype antibody Anti-Id或 The variable region of the antibody molecule not only can specifically bind with the corresponding antigen, but also can play the role of antigen due to their certain amino acid sequence and spatial configuration. The determinants that induce heterologous, allogenic and self-producing antibodies are called Idiotype (Id) determinants of antibodies. Antibodies with Id are called idiotypic antibodies (Id or Ab-1). Id can be recognized by another lymphocyte with the corresponding antigen receptor to produce anti-ldiotype antibody Anti-Id or
