Quantity: 1 mg
Unit Size: Each
• 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_dof 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
