  "abstract": "Understanding spontaneous genome rearrangement requires mapping both error-free and mutational repair outcomes, particularly error-free sister chromatid exchanges (SCEs). Here, we present a sci-L3-Strand-seq protocol capturing SCEs across thousands of single cells from 12-16 independent samples in one experiment. We detail steps for cell labeling, sample banking, nucleosome depletion, in situ combinatorial barcoding, enrichment of BrdU-labeled cells, and nascent strand ablation. We then detail linear amplification, reverse transcription, and second-strand synthesis. Libraries are typically sequencing-ready within three days from frozen cells. For complete details on the use and execution of this protocol, please refer to Chovanec et al.¹.",
