Pig embryo kidney and BHK-21 cells infected with tick-borne encephalitis virus synthesize a nonvirion antigen differing in its immunological properties from the virion antigens. The antigen has a high thermostability. According to the results of ultrafiltration and gel filtration, its molecular weight is approximately 70-100 kilodaltons. Electrophoretic analysis in polyacrylamide gel showed the molecular weight of a polypeptide isolated from the precipitation band formed by this low molecular antigen to differ from molecular weights of virion and high molecular virus-specific nonvirion proteins and to be about 20 kilodaltons. This polypeptide is assumed to be a subunit of the analyzed nonvirion low molecular antigen.
感染蜱传脑炎病毒的猪胚胎肾细胞和BHK - 21细胞合成一种非病毒体抗原，其免疫特性与病毒体抗原不同。该抗原具有很高的热稳定性。根据超滤和凝胶过滤结果，其分子量约为70 - 100千道尔顿。聚丙烯酰胺凝胶电泳分析表明，从这种低分子抗原形成的沉淀带中分离出的一种多肽的分子量与病毒体和高分子量病毒特异性非病毒体蛋白的分子量不同，约为20千道尔顿。这种多肽被认为是所分析的非病毒体低分子抗原的一个亚基。
