Rhod-2

Rhod-2 is a specialized dye used in scientific research to measure calcium levels inside cells. Calcium is important for many cell functions, especially in the heart and nervous system. Rhod-2 fluoresces—glows—when it binds to calcium, allowing scientists to visualize and quantify calcium concentrations using microscopes and cameras. This helps researchers understand how cells respond to signals and maintain balance. Rhod-2 is preferred because it is sensitive, can be targeted to specific cell parts, and provides clear, reliable readings of calcium dynamics in live cells.
