Calcein Blue
CAS No. : 54375-47-2
MCE 国际站：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：Fluorescent Dye
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.

文献和实验一般指青霉属（Penicillium）。为分布很广的半知菌纲中的一属，和曲霉属有亲缘关系，有二百几十种，代表种是灰绿青霉（ Penicillium glaucum），从土壤或空气中很易分离，分枝成帚状的分生孢子从菌丝体伸向空中，各顶端的小梗产生链状的青绿—褐色的分生孢子。根据分生孢子顶端的膨大与否，与曲霉属（ AsPergillus）相区别。其语源来自其形状（帚状， Penicillus）。子囊壳为封闭型。该属菌产生一种特殊物质。自从弗莱明（ A． Fleming， 1929）发现特异
