Anti-benzo[a]pyrene (B[a]P)-like autoantibodies (autoAb) have been characterized in sera of patients with epithelial tumors. Circulating immune complexes (CIC) from these sera have been analysed after polyacrylamide gel electrophoresis (PAGE) under non-denaturing conditions. Immunoblotting was performed using a monoclonal antiidiotypic antibody (Ab), internal image of conjugated B[a]P called AIB1 and anti-human immunoglobulins (Ig). An immunoreactivity was seen only with AIB1 Ab, suggesting the presence of a 'B[a]P-like' binding protein. Additional studies showed that this immunoreactivity is not associated with an 18- to 20-kDa protein previously identified in the same CIC.
在上皮肿瘤患者血清中已鉴定出抗苯并[a]芘(B[a]P)样自身抗体(自身抗体)。在非变性条件下进行聚丙烯酰胺凝胶电泳(PAGE)后,对这些血清中的循环免疫复合物(CIC)进行了分析。使用单克隆抗独特型抗体(抗体)、称为AIB1的结合B[a]P的内影像以及抗人免疫球蛋白(Ig)进行免疫印迹。仅用AIB1抗体观察到免疫反应性,表明存在一种“B[a]P样”结合蛋白。进一步研究表明,这种免疫反应性与先前在同一CIC中鉴定出的18至20 kDa蛋白无关。
