Fluo-8® Calcium Indicators
Fluo-3 and Fluo-4 were the most commonly used visible light-excitable calcium indicators. However, Fluo-3 AM and Fluo-4 AM are only moderately fluorescent in live cells upon esterase hydro-lysis, and require harsh cell loading conditions to maximize their cellular calcium responses.

Cal-520™ Calcium Indicators
Cal-520™ provides the most robust homogeneous fluorescence-based assay tool for detecting intracellular calcium mobilization.

Cal-590™ Calcium Indicators
Calcium measurement is critical for numerous biological investigations. Fluorescent probes that show spectral responses upon binding calcium have enabled researchers to investigate changes in intracellular free calcium concentrations by using fluorescence microscopy, flow cytometry, fluorescence

Cal-630™ Calcium Indicators
X-Rhod-1 is commonly used as a red fluorescent calcium indicator. However, X-Rhod-1 is only moderately fluorescent in live cells upon esterase hydrolysis, and has very small cellular calcium responses.

Rhod-4™ Calcium Indicators
Rhod-2 is the most commonly used red fluorescent calcium indicators. However, Rhod-2 AM is only moderately fluorescent in live cells upon esterase hydrolysis, and has very small cellular calcium responses.

Ratiometric Calcium Indicators
Among the ratiometric calcium indicators, Fura-2 and Indo-1 are most commonly used. BTC is another excitation-ratioable calcium indicator.
