Description
Suitable for determination of micromolar amounts of calcium
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
General Description
• Arsenazo III is highly specific for calcium and produces absorbance peaks in the 600-660 nm range
• It reacts in slightly acidic conditions, and is soluble in alcohol and semi-soluble in water
Application
• Arsenazo III can detect calcium in permeabilized cells; it is also capable of detecting uranium and thorium
• Arsenazo III has been used in vitro to measure intracellular Ca2+ levels in live neurons alongside patch clamp methods
