Largescale sequencing of RNAs from individual cells can reveal patterns of gene, isoform and allelic expression across cell types and states11 However, current singlecell RNAsequencing (scRNAseq) methods have limited ability to count RNAs at allele and isoform resolution, and longread sequencing techniques lack the depth required for largescale applications across cells22,33.
