Calcein Blue

CAS No. : 54375-47-2

MCE 站：Calcein Blue

产品活性：Calcein Blue 是一种不渗透膜的荧光染料，是一种含有亚氨基二乙酸结构的香豆素衍生物。Calcein Blue 也是一种金属荧光变色指示剂。

研究领域：Others

作用靶点：Others

In Vitro: The fluorescence of Calcein Blue (CB) is quenched by the Fe²⁺ ion in the Calcein Blue-Fe²⁺ complex. When dopamine is added to a solution of the Calcein Blue-Fe²⁺ complex, a dopamine-Fe²⁺ complex is formed as the result of a ligand exchange reaction between Calcein Blue and dopamine which permits the fluorescence from Calcein Blue to be recovered. The fluorescence intensity at the wavelength of 440 nm (at the excitation wavelength of 340 nm) is found to be proportional to the concentration of the dopamine added to the Calcein Blue-Fe²⁺ complex solution, which permits dopamine to be quantitatively determined. The Calcein Blue-Fe²⁺ complex shows a high selectivity for dopamine among the catecholamines and related compounds examined.
