The 10x Genomics Chromium platform is a microfluidics-based system for high-throughput single-cell genomics, enabling simultaneous analysis of thousands of individual cells. By encapsulating single cells in barcoded droplets, it supports applications such as single-cell gene expression, combined multiome profiling, and immune repertoire analysis. This technology reveals cellular heterogeneity and regulatory mechanisms that are not detectable with bulk methods, advancing research in fields including cancer, immunology, and neuroscience.
