AF488 NHS ester

AF488 is a bright and photostable dye. 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.

AF488是一种明亮且耐光的染料。由于其高亲水性，这是敏感蛋白质和抗体标记的首选染料。这种染料适用于许多苛刻的应用，包括显微镜。

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.

从化学角度来看，AF488是磺化罗丹明染料罗丹明110（R110）。与其他罗丹明类似，它可以作为5-和6-异构体，具有几乎相同的光物理性质。

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.

但是，异构体需要分离——否则，使用混合异构体染料可能会在标记产品的HPLC或电泳分离过程中导致双峰。本品为同分异构体纯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.

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