Rhod-FF (Potassium Salt) by Molecular Depot is a rhod-FF potassium salt, an analogue of the cell-impermeant calcium indicator rhod-2. Fluorination lowers the calcium affinity, so the indicator keeps responding where rhod-2 would already be saturated. It is used to measure high intracellular calcium levels by red fluorescence, in permeabilized cells, after microinjection and in cell-free systems. Each unit contains 50 µg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
