The immune cell profiling capabilities of single-cell RNA sequencing (scRNA-seq) are powerful tools that can be applied to the design of theranostic monoclonal antibodies (mAbs). Using scRNA-seq to determine natively paired B-cell receptor (BCR) sequences of immunized mice as a starting point for design, this method outlines a simplified workflow to express single-chain antibody fragments (scFabs) on the surface of yeast for high-throughput characterization and further refinement with directed evolution experiments. While not extensively detailed in this chapter, this method easily accommodates the implementation of a growing body of in silico tools that improve affinity and stability among a range of other developability criteria (e.g., solubility and immunogenicity).
单细胞 RNA 测序（scRNA-seq）的免疫细胞分析能力是一种强大的工具，可以应用于治疗性单克隆抗体（mAb）的设计。该方法使用 scRNA-seq 来确定免疫小鼠天然配对的 B 细胞受体（BCR）序列作为设计的起点，概述了一种简化的工作流程，用于在酵母表面表达单链抗体片段（scFabs），以进行高通量表征，并通过定向进化实验进一步改进。虽然本章没有详细介绍，但该方法很容易适应越来越多的计算工具的实施，这些工具可以提高亲和力和稳定性，同时满足其他一系列可开发性标准（例如溶解度和免疫原性）。
