产品描述:AF488 is a bright and photostable dye, equivalent of Alexa Fluor® 488. Due to its high hydrophilicity, this is a dye of choice for the labeling of sensitive proteins and antibodies. The dye is useful for many demanding applications, including microscopy.

From the chemical standpoint, AF488 is a sulfonated rhodamine dye Rhodamine 110 (R110). Like other rhodamines, it is available as 5- and 6-isomers, which have almost identical photophysical properties. The isomers need to be separated though - otherwise, use of mixed isomer dye can lead to doubled peaks during HPLC or electrophoresis separations of the labeled products. This product is an isomerically pure 5-AF488.

This NHS ester is an amine reactive dye, it can label amine groups in proteins, peptides, amino-modified oligos, and other target molecules.

AF488是一种明亮且耐光的染料,相当于Alexa Fluor®488。由于其高亲水性,这是标记敏感蛋白和抗体的首选染料。这种染料可用于许多苛刻的应用,包括显微镜。

从化学观点来看,AF488是磺化罗丹明染料罗丹明110(R110)。与其他罗丹明一样,它也有5-和6-异构体,它们具有几乎相同的光物理性质。然而,需要分离异构体,否则,在HPLC或电泳分离标记产品时,使用混合异构体染料会导致双峰。该产品为异构纯5-AF488。

这种NHS酯是一种胺活性染料,它可以标记蛋白质、肽、氨基修饰的寡聚物和其他目标分子中的胺基。
