How to Learn Flow Cytometry and Cell Sorting: From Light Scatter and Fluorescence to Gating, Spectral Unmixing and Single-Cell Decisions
Learning goal: Build a learner from “a machine counts fluorescent cells” to a professional understanding of how single-cell optical measurements become population claims, how compensation or spectral unmixing changes those measurements, how gates create classifications, and how sorting turns a classification into a physical sample. Scope boundary: Single-Cell and Spatial Omics owns transcriptomic/proteomic state maps;…
