疫苗是人类伟大的发明之一,拯救了无数的生命并改善了全世界人民的健康。随着人口的增长和微生物适应性的提高,全球疫苗市场的需求越来越高。尤其是自2019年底新冠疫情爆发以来,在全球范围内展开了一场协同作战的疫苗竞赛:从发现新冠病毒后短短一年的时间里,新冠疫苗研发得到了空前的发展,其中包括mRNA疫苗、病毒载体疫苗和基于蛋白质的疫苗等。

准确、非标记的分子定量及动力学分析是高效疫苗研发的基础,满足所需的分析通量是早期发现和工艺开发的主要挑战。赛多利斯Octet®非标记分子互作分析系统具备高通量、易于操作、分析精度高的特点,通过免标记的生物层干涉(BLI)技术和灵活多样的生物传感器,提供实时的结合动力学、特异性及亲和力、免疫反应、表位图谱以及疫苗滴度等信息,以快速了解抗原靶点及疫苗候选药物特征。

作为成熟的分析方法,Octet®已协助多种疫苗的研究和开发(详见表1),并应用于多个关键环节,包括表位设计、识别及特征分析,病原体多样性和分布,抗体亲和力测定,宿主免疫反应特征、多样性和分布,核酸和分子病原体-宿主相互作用研究,以及治疗药物及临床研究等。
