Multicolor multicycle molecular profiling with quantum dots for single-cell analysis.

ABSTRACT: Here we present a detailed protocol for molecular profiling of individual cultured mammalian cells using multicolor multicycle immunofluorescence with quantum dot probes. It includes instructions for cell culture growth and processing (2 h + 48-72 h for cell growth), preparation and characterization of universal quantum dot probes (4.5 h + overnight incubation), cyclic cell staining (∼4.5 h per cycle) and image analysis (varies by application). The use of quantum dot fluorescent probes enables highly multiplexed, robust quantitative molecular imaging with a conventional fluorescence microscopy setup, whereas the probe preparation methodology, using a self-assembly between protein A-decorated universal quantum dots and intact primary antibodies, offers a fast, simple and purification-free r
