ZnAF-2F DA ≥95% (by HPCE)

Supplier: Adipogen

Description: For application to living cells, the diacetyl derivative of ZnAF-2F, ZnAF-2F DA, was synthesized. ZnAF-2F DA can permeate through the cell membrane, and is hydrolyzed by esterase in the cytosol to yield ZnAF-2F, which is retained in the cells. Using ZnAF-2F DA we could measure the changes of intracellular Zn2+ in cultured cells and hippocampal slices. Spectral data: lambdaex 492nm; lambdaem 515nm in PBS.

ZnAF-1F DA ≥95% (by HPCE)

Supplier: Adipogen

Description: For application to living cells, the diacetyl derivative of ZnAF-1F, ZnAF-1F DA, was synthesized. ZnAF-1F DA can permeate through the cell membrane, and is hydrolyzed by esterase in the cytosol to yield ZnAF-1F, which is retained in the cells. ZnAF-1F DA has been used to measure the changes of intracellular Zn2+ in cultured cells and hippocampal slices. Spectral data: lambdaex 492nm; lambdaem 514nm in PBS.

ZnAF-2 DA ≥90% (by HPCE)

Supplier: Adipogen

Description: Suitable for the fluorimetric detection of Zn2+ (after esterase hydrolysis). Spectral data: lambdaex 492nm; lambdaem 515nm in PBS.

ZnAF-1 DA ≥90% (by HPCE)

Supplier: Adipogen

Description: Suitable for the fluorimetric detection of Zn2+ (after esterase hydrolysis). Spectral data: lambdaex 492nm; lambdaem 515nm in PBS.

ZnAF-1 ≥95% (by HPCE)

Supplier: Adipogen

Description: A membrane-impermeable ethylenediaminofluoresceinyl compound that acts as a high-affinity Zn2+-specific fluorescent probe. Spectral data: lambdaex 492 nm; lambdaem 514 nm in PBS.

ZnAF-1F ≥90% (by HPCE)

Supplier: Adipogen

Description: ZnAF-1F and ZnAF-2F do not fluoresce in the presence of other biologically important cations such as Ca2+ and Mg2+, and are insensitive to change of pH. The complexes with Zn2+ of previously developed ZnAFs, ZnAF-1, and ZnAF-2 decrease in fluorescence intensity below pH 7.0 owing to protonation of the phenolic hydroxyl group of fluorescein, whose pKa value is 6.2. On the other hand, the Zn2+ complexes of ZnAF-1F and ZnAF-2F emit stable fluorescence under neutral and slightly acidic conditions because the pKa values are shifted to 4.9 by substitution of electron-withdrawing fluorine at the ortho position of the phenolic hydroxyl group. Spectral data: lambdaex 492nm; lambdaem 517nm in PBS.

On the other hand, the Zn2+ complexes of ZnAF-1F and ZnAF-2F emit stable fluorescence around neutral and slightly acidic conditions because the pKa values are shifted to 4.9 by substitution of electron-withdrawing fluorine at the ortho position of the phenolic hydroxyl group.
