Cyanine5.5 Maleimide|Cy5.5 Mal

Cyanine 5.5应用非常广泛，不仅可用于生物大分子的标记，还被用作一些小分子的衍生化试剂。maleimide（马来酰亚胺）常被用来标记巯基,Cyanine5.5 Maleimide与其他标记巯基的荧光试剂(如FITC，TRITC等)相比，它反应选择更高。Cyanine5.5 Maleimide是近红外染料，除了用于标记多肽，蛋白和寡核苷酸氨基外，也常被用于小动物活体成像。因为它避开了很多物质都有吸收的可见光区，吸收的近红外光在生物组织中的穿透深度较大，而激发的荧光受生物组织本底的影响较少，所以能够在深层组织产生信号。尤其是在700～900 nm的范围中，水和血红蛋白的吸收都很少，近红外光可以深入组织内部多达15 cm。同时，这类染料还拥有紫外光区染料和同位素标记无法具备的生物安全性。Cyanine 5.5 (cy 5.5）是常用的近红外荧光染料。

cyanine 5.5 Maleimide需要共溶剂，但由于其疏水性比Cyanine7弱，应用更为广泛。陕西新研博美生物提供三乙胺盐酸盐（triethylammonium salts）形式的cyanine 5.5 Maleimide，较其他公司钾盐形式的cyanine 5.5 Maleimide更易容，在光学性质，反应性相同的情况下，拥有更好的溶解性。

cyanine 5.5 Maleimide（马来酰亚胺）广谱学性质与Alexa Fluor 680 Maleimide和DyLight 680 Maleimide类似，可作为其替代物。
