In this work, we show that antibodies to baculovirus recombinant DNA polymerase of human cytomegalovirus are present in human sera during natural infection. Specific antibody was found to be of the immunoglobulin G class, produced at low titers only for a short period of time at the beginning of acute infection and not detectable in sera from patients with a convalescent or a latent phase of infection. These results were compared with those obtained with procaryotically expressed p52, the polymerase accessory protein.
在本研究中,我们表明,在自然感染期间,人血清中存在针对人巨细胞病毒杆状病毒重组DNA聚合酶的抗体。发现特异性抗体属于免疫球蛋白G类,仅在急性感染开始时短时间内以低滴度产生,在处于恢复期或感染潜伏期的患者血清中无法检测到。将这些结果与用原核表达的聚合酶辅助蛋白p52获得的结果进行了比较。
