Calcium & Other Ion Indicators

Membrane-permeant form of Fluo-4 calcium indicator.

Membrane-permeant AM ester form of Fluo-3 that can be loaded into cells via incubation. Because of the relatively low water solubility of the AM ester, Pluronic F-127, a mild detergent, is often used as a dispersing agent to facilitate dye loading.

5(6)-CFDA (full name: 5-(and-6)-Carboxyfluorescein diacetate) is membrane-permeant and thus can be loaded into cells via incubation. Once inside cells, CFDA is hydrolyzed by intracellular esterases to carboxyfluorescein (see #51013 ).

The membrane-permeant form of DMNP-EDTA (also known as DM-Nitrophen™), a photolyzable calcium chelator that can be used to release a pulse of calcium when exposed to light.

Membrane-permeant AM ester form of Mag-Fluo-4, a fluorescent magnesium and calcium ion indicator that is an analog of Fluo-4.

Membrane-impermeant form of Mag-Fluo-4, a fluorescent magnesium and calcium ion indicator that is an analog of Fluo-4.

Fluo-4, pentapotassium is membrane-impermeant calcium indicator. It can be loaded into cells via microinjection or scrape loading.

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.

Membrane-impermeant calcium indicator that can be loaded into cells via microinjection or scrape loading. For the membrane-permeable AM ester form of Rhod-590, see 50025.

Membrane-permeant form of Rhod-590 that can be loaded into cells via incubation.

Nonionic detergent useful for solubilizing hydrophobic compounds to facilitate cell loading.

Zinquin is an UV-excitable, blue fluorescent zinc indicator. Zinc is believed to be involved in the suppression of apoptosis and thought to play important roles in many neural activities.
