Dinitrophenyl conjugates of poly-L-lysine, varying in percentage conjugation and molecular weight have been found to induce skin reactivity and precipitating antibodies in guinea pigs. At best, 40 per cent of immunized animals developed delayed and immediate responses to DNP-polylysine, which is believed to reflect constitutional differences among the animals assayed. Only those animals capable of responding to DNP-polylysine, responded to an immunologically distinct poly-alpha-amino acid consisting of glutamyl and lysyl residues ("copolymer glu-lys"). The percentage of animals responding to the DNP-polylysine antigen decreased as the degree of DNP conjugation increased.
已发现不同偶联百分比和分子量的聚-L-赖氨酸二硝基苯基偶联物可在豚鼠中诱导皮肤反应性并产生沉淀抗体。最多有40%的免疫动物对二硝基苯基聚赖氨酸产生延迟和即时反应,这被认为反映了所检测动物之间的体质差异。只有那些能够对二硝基苯基聚赖氨酸作出反应的动物,才会对由谷氨酰基和赖氨酰基残基组成的免疫学上不同的聚α-氨基酸(“共聚物谷氨酰-赖氨酸”)作出反应。随着二硝基苯基偶联程度的增加,对二硝基苯基聚赖氨酸抗原作出反应的动物百分比下降。
