Azoproteins have been prepared with azocomponents possessing two serologically active groups. On immunization with such antigens immune sera were obtained containing two separate, unrelated antibodies, each specific for one of the two groups and separable by absorption. In other cases one of the two structures was dominant, in that antibodies were formed only towards this and not towards the other grouping. The specificity of the antibodies was in general found to be influenced to some extent by the presence of a second group in the antigen. The relevancy of these observations for antibodies directed against natural antigens has been noted.
Azoproteins已经用具有两个免疫活性基团的偶氮组分制备出来。通过对这种抗原免疫,获得了含有两种分离的、无关的抗体的免疫血清,每种抗体具体针对其中一种基团,并可通过吸附分离。在其他情况下,两种结构中的一种是主导的,即只对这一种形成抗体,而不对另一种形成抗体。通常发现抗体的特异性在一定程度上受到抗原中第二基团的影响。已经注意到这些观察结果对针对天然抗原的抗体的相关性。
