Bright, red fluorescent lysosomal label for live-cell imaging—no fixation, staining, or cell lysis required. Visualize lysosomal morphology and dynamics in real time, over hours to days, in living cells. Delivered using Montana Molecular’s Big Sky BacMam vector for enhanced expression across a wide range of cell types, including primary cultures and iPSCs. Lysosomal targeting is achieved via Lamp2. Ideal for dynamic, non-destructive studies of lysosomal organization, cellular phenotypes, and high-content imaging.
