病毒可在被感染的细胞中复制抗原物质,这类抗原物质分布于细胞外膜上或分泌到周围环境中,并且引起被感染的宿主的主动免疫反应.病毒不仅可以引起疾病,而且也可以改变某些疾病的流行过程,这说明早期发现病毒感染,确定其临床意义,改进检查病原体类型的方法均很重要. 病毒抗原和受体大量集中于细胞外膜——质膜上,它们参与各种免疫反应,包括激活补体的不同成分,从而导致被感染细胞的溶解。借助各种细胞外或细胞内指示系统以检查补体结合反应结果,此反应至今作为检查病毒抗原和抗体的主要方法. 经典的补体结合反应是将指示系统的红细胞和相应溶解它们的溶血素(抗血清)一
Viruses can replicate antigenic material in infected cells, which are distributed on the extracellular membrane or secreted into the environment and cause an active immune response in infected hosts. The virus can not only cause disease, but also change The prevalence of certain diseases indicates that it is important to identify the early stages of viral infection, determine its clinical relevance, and to improve the way it can be used to examine the types of pathogens. Viral antigens and receptors are heavily concentrated on the extracellular and plasma membranes, and they are involved in various Immune responses, including activating different components of complement, result in the lysis of infected cells. This reaction has so far served as the primary method of examining viral antigens and antibodies by means of various extracellular or intracellular signaling systems.The classic complement fixation reaction is directed to red blood cells of the system and the corresponding hemolysin Serum) one
