背景介绍
SARS-CoV-2是导致COVID-19大流行的病原体,其表面的刺突蛋白(Spike,S蛋白)以三聚体(Trimer)形式存在,介导病毒与宿主细胞ACE2受体的结合及膜融合过程,是疫苗研发中最重要的靶抗原。随着变异株的不断出现,XBB.1等新型亚变异株凭借更强的免疫逃逸能力,对现有疫苗提出了新的挑战,全球已有多款基于XBB系列变异株抗原的新一代新冠疫苗获批或进入临床开发阶段。
在上述亚单位疫苗(Subunit Vaccine)的研发与生产中,对核心抗原——刺突三聚体的精确定量检测,是确保疫苗批次间一致性、有效性和质量可控性的关键环节。ACROBiosystems开发的SARS-CoV-2 Spike Trimer (XBB.1) ELISA试剂盒(RAS-A149)正是为满足这一需求而设计。该试剂盒基于双抗体夹心酶联免疫吸附法,采用预包被抗刺突三聚体抗体的微孔板,配合生物素化检测抗体和链霉亲和素-HRP检测体系,可对样本中的XBB.1刺突三聚体抗原进行准确定量。试剂盒经验证灵敏度达12.5 ng/mL,适用于新冠亚单位疫苗研发中的工艺开发、中间品控制及成品放行检测,为疫苗质量评估提供了快速、标准化的分析工具。
