Europium(III) cryptate（Cat No.:M106189） is a luminescent complex involving the europium ion (Eu^3+), typically chelated within a macrocyclic structure known as a cryptand. This chemical complex is highly valued for its exceptional stability and intense, sharp emission properties when exposed to ultraviolet light. The europium ion’s ability to emit red fluorescence makes europium(III) cryptate a popular choice in various high-sensitivity biological assays, including time-resolved fluorescence resonance energy transfer (TR-FRET) applications. These characteristics are harnessed in scientific research to detect and quantify molecular interactions and dynamics.
