Antibodies (Abs) are among the most important class of biologicals, showcasing a high therapeutic and diagnostic value. In the global therapeutic Ab market, fully-human monoclonal Abs (FH-mAbs) are flourishing thanks to their low immunogenicity and high specificity. The rapidly emerging field of single-cell technologies has paved the way to efficiently discover mAbs by facilitating a fast screening of the antigen (Ag)-specificity and functionality of Abs expressed by B cells. This review summarizes the principles and challenges of the four key concepts to discover mAbs using these technologies, being confinement of single cells using either droplet microfluidics or microstructure arrays, identification of the cells of interest, retrieval of those cells and single-cell sequence determination required for mAb production. This review reveals the enormous potential for mix-and-matching of the above-mentioned strategies, which is illustrated by the plethora of established, highly integrated devices. Lastly, an outlook is given on the many opportunities and challenges that still lie ahead to fully exploit miniaturized single-cell technologies for mAb discovery.

用于单克隆抗体发现的小型化单细胞技术

抗体 (Abs) 是最重要的一类生物制品,具有很高的治疗和诊断价值。在全球治疗性抗体市场中,全人源单克隆抗体(FH-mAb)因其低免疫原性和高特异性而蓬勃发展。快速兴起的单细胞技术领域通过促进 B 细胞表达的抗体的抗原 (Ag) 特异性和功能的快速筛选,为有效发现 mAb 铺平了道路。本综述总结了使用这些技术发现 mAb 的四个关键概念的原则和挑战,即使用液滴微流体或微结构阵列限制单个细胞、识别感兴趣的细胞、检索这些细胞和所需的单细胞序列确定用于 mAb 生产。这篇综述揭示了混合搭配上述策略的巨大潜力,大量成熟的、高度集成的设备就说明了这一点。最后,展望了充分利用微型单细胞技术进行 mAb 发现方面仍存在的许多机遇和挑战。
