Rhod-2 triammonium

Calcium Ion Probe

Rhod-2 triammonium is a cell impermeant red fluorescent calcium ion probe that targets calcium binding. This reagent exhibits a notable increase in fluorescence intensity upon calcium binding, with excitation maxima shifting from 549 nm in the calcium-free state to 552 nm in the calcium-bound state, and emission maxima at 581 nm. Rhod-2 triammonium is ideal for studying intracellular calcium dynamics and monitoring calcium fluctuations in live cells without the spectral shifts associated with UV-excitable indicators.
