Genetically Encoded Biosensors
LumiRDT® (Real-time Detection Technology) represents LumiSTAR's breakthrough platform of genetically encoded biosensors that transform cellular analysis through superior protein-based indicators.
Unlike traditional chemical fluorescent dyes that suffer from photobleaching, cellular toxicity, and loading variability, LumiRDT® biosensors are genetically encoded within cells, providing unprecedented advantages for drug discovery and biological research.

Unlabeled cultured cells are largely transparent, making reliable visualization and morphological analysis of cells and sub‑cellular structures difficult.
LumiRDT engineered viral particles, encoding fluorescent protein reporters, are added to the culture to transduce the cells.
After entry, transduced cells express fluorescent proteins that selectively localize to specific organelles, producing distinct intracellular signals.
These fluorescence patterns are captured by fluorescence microscopy, enabling high‑content, quantitative analysis of cellular architecture and function.
