Fluo-4 AM is a cell-permeable dye that detects calcium in live cells, emitting bright green fluorescence upon Ca²⁺ binding (494/506 nm). It’s ideal for microscopy, flow cytometry, and screening assays. Fluo-4 AM offers higher sensitivity and lower toxicity than Fluo-3, making it perfect for real-time calcium signaling studies in cell biology and drug research.
