Simultaneous DNA, RNA, and Protein Analysis from Single Cells Using a High-Throughput Microfluidic Workflow for Resolution of Genotype-to-Phenotype Modalities.

Understanding the genomic landscape of cancer in single cells can be valuable for the characterization of molecular events that drive evolution of tumorigenesis and fostering progress in identifying druggable regimens for patient treatment scenarios. We report a new approach to measure multiple modalities simultaneously from up to 10,000 individual cells using microfluidics paired with next-generation sequencing. Our procedure determines targeted protein levels, mRNA transcript levels, and somatic gDNA sequence variations including copy number variants. This approach can resolve over 20 proteins, 100s of targeted transcripts, and DNA amplicons.
