Calcium Indicators & Chelators
Biotium offers a wide range of calcium indicator dyes, including Fluo-4, a bright and cell permeable dye that is used for high-throughput screening.
The calcium indicator dyes vary in their calcium dissociation constant (Kd), color and brightness. The AM ester versions are cell permeable, and hydrolyzed by intracellular esterases to release the fluorescent dye. Please see our Fluorescent Ion Indicator brochure to select the dye that is right for your experimental needs.
