Description

Fura-2 pentapotassium is a scaled fluorescent dye that can be used for intracellular calcium imaging with the Kd value of 140 nM. Fura-2 pentapotassium has an emission wavelength of 510 nm and excitation wavelengths of 340 nm or 380 nm and the ratio of 340/380 fluorescence intensity is proportional to the intracellular Ca2+ level[1][2].

In Vitro

Fura-2 pentapotassium (10 μM, 2 min) can be used to detect changes in the concentration of calcium ions in neutrophils of heparinized peripheral blood[1].
Fura-2 pentapotassium (10 μM, 5 min) can be used as a calcium probe to assess the distribution of calcium ions within heart mitochondria without affecting the activity of it in rat[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
