Invitrogen™ eBioscience™ Fura-2 AM Dye

Description

• Upon binding Ca 2+ , the excitation spectrum of Fura-2 shifts to shorter wavelengths between 300 and 400nm, while the peak emission remains steady around 510nm The K d of Fura-2 is highly dependent on pH, temperature, ionic strength and viscosity of the cytosol, thus great care should be taken when non-standard conditions are used Molecular weight: 1001.86g/mol Peak excitation: variable depending on the concentration of free Ca 2+ , between 300 and 400nm Peak emission: 510nm Reconstitute in high-quality, freshly opened DMSO
• Once reconstituted, protect from light and store at −20°C
• Avoid freeze-thawing
