Calcium Indicators & Chelators

Biotium offers a wide range of calcium indicator dyes, including Fluo-4 AM Ester, 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. See our complete selection of Calcium & Other Ion Indicators, or download the Ion Indicator Brochure to learn more.

    5,5′-Difluoro BAPTA, Tetrapotassium Salt

    From: $268 Sizes: 100 mgCatalog #: 50006

    BAPTA and its derivatives are calcium chelators that are commonly used to form calcium buffers with well-defined calcium concentrations. By injecting the chelators into cells or by incubating cells with the AM ester form of the chelators, one can control the cytosolic calcium concentration, an important means to study the roles of calcium.
