BCECF AM - green fluorescent pH indicator
BCECF AM is the most popular green fluorescent, intracellular pH indicator. BCECF has a pKa of ~7, and exhibits pH-dependent, dual-excitation properties (Ex/Em 430nm/535nm and 490nm/535nm) for ratiometric analysis. Ratiometry is optimal for imaging applications, and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology. For HTS applications, BCECF can also be used in non-ratiometric mode using standard fluorescein excitation and emission settings.Excitation: 450, 500 nm | Emission: 530 nm | Purity: >95%

SBFI AM - green fluorescent sodium indicator
Ratiometric sodium indicator, membrane permeableExcitation: 340, 380 nm | Emission: 505 nm | Kd: 5 mMSBFI is a UV-excitable, ratiometric green indicator for intracellular sodium (Na⁺) measurements. Ex/Em: 340/505 nm can be used to measure Na⁺-bound SBFI, and Ex/Em: 380/505 nm can be used to detect Na⁺-free SBFI. It is ~18X more selective for Na⁺ over K⁺. Ratiometry is optimal for imaging applications where quantification of intracellular Na⁺ concentrations is desired, and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology.

Fluo-2 K+ Salt - Green fluorescent calcium indicator
High-affinity calcium indicator, membrane impermeable. Compatible with flow cytometry, plate reader, and fluorescence microscopy assays. Also known as Fluo-2 High Affinity, Fluo-2 HA.Excitation: 490 nm | Emission: 515 nm | Kd: 290 nM | Purity: >95%Fluo-2 is a green fluorescent, calcium (Ca²⁺) indicator. Fluo-2 has higher Ca²⁺ affinity, superior cell loading and comparable spectral properties compared to Fluo-4. Offers superior sensitivity versus other Fluo analogues at lower Ca²⁺ concentrations.Fluo-2 K⁺ Salt is a membrane impermeable form of Fluo-2 that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.

Fluo-3 K+ Salt - Green fluorescent calcium indicator
Calcium indicator, membrane impermeable. Compatible with flow cytometry, plate reader, and fluorescence microscopy assays.Excitation: 505 nm | Emission: 525 nm | Kd: 390 nM | Purity: >95%Fluo-3 is a green fluorescent, intracellular calcium (Ca²⁺) indicator with slightly red-shifted spectral properties compared to Fluo-4. Offers a large dynamic range that can be better suited for high contrast imaging applications. Is preferred over Fluo-4 for some cell types.Fluo-3 K⁺ Salt is a membrane impermeable form of Fluo-3 that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.
