GoT-Splice protocol for multi-omics profiling of gene expression, cell-surface proteins, mutational status, and RNA splicing in human cells

Studying RNA splicing factor mutations is challenging due to difficulties in distinguishing wild -type and mutant cells within complex human tissues and inaccuracies associated with reconstructing splicing signals from short -read sequencing data. Here, we present Genotyping of Transcriptomes (GoT)-Splice, a protocol that overcomes these limitations by combining GoT with enhanced long -read single -cell transcriptome and cell -surface proteomics profiling. We describe steps for long -read library preparation and analysis, followed by cDNA re -amplification, enrichment of mutation of interest, sample indexing, and GoT library preparation.
