product description

Fluo-2 is a green fluorescent, calcium (Ca²⁺) indicator. Fluo-2 has higher Ca²⁺ affinity (Kd = 290 nM), 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.
