A water soluble, hydrophilic sulfo-Cyanine5 maleimide (Cy5® maleimide analog). We recommend this product for protein labeling, including labeling of antibodies as a perfect replacement for Cy5® maleimide. Labeled proteins can be easily separated from unreacted dye by gel filtration, spin column purification, dialysis, electrophoresis or chromatography.

An analog without sulfo groups, Cyanine5 maleimide, is also available.

水溶性、亲水性磺基-Cyanine5 马来酰亚胺(Cy5® 马来酰亚胺类似物)。 我们推荐该产品用于蛋白质标记,包括标记抗体作为 Cy5® 马来酰亚胺的完美替代品。 通过凝胶过滤、旋转柱纯化、透析、电泳或色谱法,可以很容易地将标记的蛋白质与未反应的染料分离。

也可使用不含磺基的类似物 Cyanine5 马来酰亚胺。
