Fluo-2, AM is one of the original Fluo series of Ca2+ indicators invented by Roger Tsien in the 1980s. Fluo-2, AM has been found to be much brighter (1.5x) than Fluo-4, AM in cellular experiments. The increased brightness of Fluo-2 is partly attribut..

Fluo-3, AM is a membrane permeant probe and can be passively loaded in cells by simple incubation. Once inside the cell, Fluo-3 becomes fluorescent in the presence of free Ca2+. Fluo-3 AM is widely used in flow cytometry, confocal laser scanning micr..

Fluo-4, AM is a membrane permeant probe and can be passively loaded in cells by simple incubation. Once inside the cell, Fluo-4 becomes fluorescent in the presence of free Ca2+. Fluo-4 AM is widely used in flow cytometry, confocal laser scanning micr..

Rhod-2, AM is a long wavelength cell-permeant Ca2+ indicator. It can be loaded into cells via incubation and used for quantifying intracellular Ca2+ concentration.   Specifications 1. Ex/Em: 550/578 nm 2. Detection Method: Fluorescent ..

Coelenterazine is a bioluminescence probe for measuring Ca2+ concentration in cells with a high sensitivity and large dynamic range. Coelenterazine (native form) is a luminescent enzyme substrate for apoaequorin and Renilla luciferase. The aequorin c..

MQAE is a 6-methoxyquinolinium derivative and is a fluorescent indicator for intracellular Cl–. This dye detects the ion via diffusion-limited collisional quenching. MQAE has greater sensitivity to Cl– and a higher fluorescence quantum yield than SPQ..

The chloride indicator MEQ has absorption/emission maxima ~344/440. MEQ can be reduced to create the cell-permeant dihydro-MEQ (DiH-MEQ) which can be passively loaded into cells and subsequently oxidized to the chloride-sensitive MEQ.   Spec..

The chloride indicator SPQ has absorption/emission maxima ~344/443 and detects Cl– via diffusion-limited collisional quenching.   Specifications 1. Ex/Em: 344/443 nm 2. Detection Method: Fluorescent 3. Molecular Formula: C13H15NO4S ..
