Description

Biochem/physiol Actions

Low-affinity fluorescent Ca2+ probe for measuring relatively high [Ca2+].
Rhod-5N is a low-affinity fluorescent Ca2+ probe (Kd = 320 μM) that is preferred over high-affinity probes, such as Rhod-2 (Kd = 570 nM), for measuring [Ca2+] when very little buffering can be tolerated or in subcellular compartments where relatively high Ca2+ levels are expected, such as mitochondria (MT) and endoplasmic reticulum (ER). Ex/Em = 551/576 nm.

Caution

Hygroscopic
