      Description
      OverviewMembrane-permeable version of FLUO 3 (Cat. No. 343244). Unlike all other Ca2+ indicators, FLUO 3/AM is non-fluorescent until it is hydrolyzed in the cell by cellular esterases. It is insensitive to Mg2+.

      Revision17-December-2018 JSW
      Synonyms1-[2-Amino-5-(2,7-dichloro-6-hydroxy-3-oxo-3H-xanthen-9-yl)]-2-(2ʹ-amino-5ʹ-methylphenoxy)ethane-N,N,Nʹ,Nʹ-tetraacetic Acid Pentaacetoxymethyl Ester
      DescriptionMembrane-permeable version of FLUO 3 (Cat. No. 343244). Cleavage of FLUO 3/AM by cytosolic esterases traps the indicator in the cell. FLUO 3 is almost nonfluorescent at resting calcium levels, but fluorescence levels increase 40-fold upon calcium binding. Unlike all other Ca2+ indicators, FLUO 3/AM is nonfluorescent until it is hydrolyzed by the cell. Since its excitation maximum is at 506 nm, this compound can be used in conjunction with caged compounds, which are released by UV light. Its relatively high Kd for Ca2+ facilitates the measurement of higher peaks of Ca2+ transients than is possible with FURA 2. FLUO 3 has an excitation maximum of 506 nm and an emission maximum of 526 nm in the presence of high and low calcium concentrations.
      FormReddish orange solid
      Recommended reaction conditionsThe FLUO 3/AM DMSO stock solution should be diluted to 1-5 µM in a physiological buffer. In some cases, use of the non-ionic detergent PLURIONIC® F-127, PROTEIN GRADE® (Cat. No. 540025) at 0.025-0.125% will assist in the dissolution of the dye in aqueous buffers. Cells are normally incubated with the dye for 20-60 min at 20-37°C.
