Fluo-4, Pentapotassium Salt, cell impermeant

Category: Products & Services > Labeling & Detection Products > Sensors & Indicators > Ion Indicators & Ionophores

Labeled calcium indicators are molecules that exhibit an increase in fluorescence upon binding Ca 2+ . Fluo-3 has been used to image the spatial dynamics of Ca 2+ signaling, in flow cytometry experiments involving photoactivation of caged chelators, second messengers, and neurotransmitters, and for cell-based pharmacological screening. Fluo-4 is an analog of fluo-3 with the two chlorine substituents replaced by fluorines, which results in increased fluorescence excitation at 488 nm and consequently higher fluorescence signal levels. Cells may be physically loaded with the cell-impermeant salt ...

Fura-FF, Pentapotassium Salt, cell impermeant

Category: Products & Services > Labeling & Detection Products > Sensors & Indicators > Ion Indicators & Ionophores

Fura-FF pentapotassium salt is a fura-2 derivative that has Ca 2+ sensitivity similar to mag-fura-2, but is relatively insensitive to Mg 2+ . This water-soluble salt form is useful for intracellular loading by microinjection, infusion from patch pipette or uptake induced by our Influx pinocytic cell-loading reagent (I-14402).
