摘要
利用杂交瘤技术制备了一种针对中间拟杆菌(Bacteroides intermedius Group I)的单克隆抗体(BIF6)。在本研究中,我们使用BIF6抗体产生细胞的培养基来鉴定抗体。采用酶联免疫吸附法检测其对中间芽孢杆菌(ⅰ、ⅱ群)、牙龈芽孢杆菌、企业芽孢杆菌、黑素原芽孢杆菌、干酪芽孢杆菌和溶糖芽孢杆菌的反应性。BIF6单克隆抗体对中间芽胞杆菌ⅰ群有特异性反应,对中间芽胞杆菌ⅱ群无特异性反应。此外,BIF6不与其他黑色拟杆菌发生反应。由于BIF6抗体与成人牙周病患者龈下斑块的临床分离物发生反应,我们建议该抗体可作为临床鉴定中间芽胞杆菌I群的工具。BIF6抗体识别的中间芽胞杆菌I群的特异性抗原位于生物体的外膜上。在80℃、pH2和12条件下灭活特异性抗原20 min。该抗原对胰蛋白酶处理敏感。
[Biological characterization of Bacteroides intermedius specific monoclonal antibody].
One monoclonal antibody (BIF6) directed against Bacteroides intermedius Group I was developed by hybridoma technology. In the present study, we used culture medium from BIF6 antibody-producing cells to characterize the antibody. Its reactivity against B. intermedius (Group I, II), B. gingivalis, B. corporis, B. melaninogenicus, B. loescheii, and B. asaccharolyticus was detected by the enzyme-linked immunosorbent assay. BIF6 monoclonal antibody specifically reacted with B. intermedius Group I, but not with B. intermedius Group II. Also, the BIF6 did not react with other black-pigmented Bacteroides. Since BIF6 antibody reacted with some clinical isolates from subgingival plaques of adult periodontal patients, we suggest that this antibody may be useful as a tool in the clinic to identify B. intermedius Group I. Specific antigen of B. intermedius Group I recognized by BIF6 antibody was located on the outer membrane of the organism. And the specific antigen was inactivated by treatment for 20 min at 80 degrees C and at pH2 and 12. Also the antigen was sensitive to trypsin treatment.
