本文介绍了一种名为SPARK-seq的高通量平台,该平台结合单细胞测序和CRISPR扰动,可同时鉴定多种细胞表面蛋白的适配体并分析其结合动力学。
原文开头
Guoyan Luo1,2†, Jia Song3,4†, Yongbo Fu3,5, Yuanjie Jiang1,6, Yuan Gao4, Zhixing Zhong3,4, Ling Li1, Yong Wei1, Hao-Ran Jia1,4, Lu Guo1, Ting Fu1, Qin Wu1,7*, Weihong Tan1,2,4* Cell surface proteins are key disease biomarkers and therapeutic targets, yet high-throughput methods for aptamer discovery targeting these proteins in situ remain limited. We introduce single-cell perturbation-driven aptamer recognition and kinetics sequencing (SPARK-seq), a high-throughput platform integrating single-cell messenger RNA and aptamer sequencing with CRISPR-based surface protein perturbation. In a single experiment, SPARK-seq simultaneously mapped 5535 distinct aptamers to eight surface proteins, capturing interactions across more than two orders of magnitude in protein abundance and spanning diverse biophysical classes. …
