Product details
Catalog number 1052E
Price for 1052E
Size / count 20x 50 µg
Ratiometric calcium indicator, membrane impermeable. Excitation: 340, 380 nm | Emission: 505 nm | Kd: 145 nM Fura-2 is the most popular UV-excitable, ratiometric green indicator for intracellular calcium (Ca²⁺) measurements. Ex/Em: 340/505 nm can be used to measure Ca²⁺-bound Fura-2, and Ex/Em: 380/505 nm can be used to detect Ca²⁺-free Fura-2. Ratiometry is optimal for imaging applications where quantification of intracellular Ca²⁺ concentrations is desired, and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology. Fura-2 K⁺ salt is a membrane impermeable form of Fura-2 that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.
The catalog number for Fura -2 K+ Salt - calcium indicator is 1052E.

Some products, including certain cell lines and biologics, require dry ice for transportation, which carries an additional fee shown clearly in your quotation. Dry ice delivery isn’t always possible to every destination due to transit time or local restrictions, so we check feasibility in advance and you must store the goods at the correct temperature the moment they arrive.
Cross-reactivity data, based on available testing, is listed under the reactivity section of the datasheet. Contact us if you need reactivity confirmed for a species not listed.
Yes, if this product requires dry ice or is classed as hazardous for transport, the additional fee will be explicitly shown in your quotation before you confirm the order, so there are no surprise charges later.
