Cyanine5.5Maleimide,Cy5.5馬來酰亞胺

Cyanine 5.5應用非常廣泛，不僅可用于生物大分子的標記，還被用作一些小分子的衍生化試劑。maleimide（馬來酰亞胺）常被用來標記巰基,Cyanine5.5 Maleimide與其他標記巰基的熒光試劑(如FITC，TRITC等)相比，它反應選擇更高。Cyanine5.5 Maleimide是近紅外染料，除了用于標記多肽，蛋白和寡核苷酸氨基外，也常被用于小動物活體成像。因為它避開了很多物質(zhì)都有吸收的可見光區(qū)，吸收的近紅外光在生物組織中的穿透深度較大，而激發(fā)的熒光受生物組織本底的影響較少，所以能夠在深層組織產(chǎn)生信號。尤其是在700～900 nm的范圍中，水和血紅蛋白的吸收都很少，近紅外光可以深入組織內(nèi)部多達15 cm。同時，這類染料還擁有紫外光區(qū)染料和同位素標記無法具備的生物安全性。Cyanine 5.5 (cy 5.5）是常用的近紅外熒光染料。

cyanine 5.5 Maleimide需要共溶劑，但由于其疏水性比Cyanine7弱，應用更為廣泛。陜西新研博美生物提供三乙胺鹽酸鹽（triethylammonium salts）形式的cyanine 5.5 Maleimide，較其他公司鉀鹽形式的cyanine 5.5 Maleimide更易容，在光學性質(zhì)，反應性相同的情況下，擁有更好的溶解性。

cyanine 5.5 Maleimide（馬來酰亞胺）廣譜學性質(zhì)與Alexa Fluor 680 Maleimide和DyLight 680 Maleimide類似，可作為其替代物。
