Rhod-2 sodium is a cell impermeant, red fluorescent calcium indicator. Rhod-2 sodium exhibits a significant shift in fluorescence intensity upon calcium binding (ex max=549 nm; calcium-free v. ex/em max=552/581 nm; calcium-bound). Unlike the UV-excitable indicators Fura-2 and Indo-1 (HY-D0121), there is no accompanying spectral shift.
- Formula: C29H22N3Na5O14

Fura-2 pentasodium is a cell-impermeable scaled fluorescent dye that can be used for intracellular calcium imaging. Fura-2 pentasodium 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.
