產品簡介：

磺化Cy7.5(sulfo Cyanine 7.5; sulfo Cy7.5)是一種發近紅外(NIR)熒光的花青素類熒光染料。磺化Cy7.5是磺化修飾過的Cy7.5，水溶性好。磺化Cy7.5的消光系數高，熒光也很亮，并且對pH不敏感，并且由于它的熒光波長（Em：797nm）恰好處于肌體組織近紅外窗口 I 的區域（肌體的血液，體液和組織此區域背景熒光弱，而長波長穿透性強），所以磺化Cy7.5常應用于小動物活體體內成像中。磺化Cy7.5可以用來標記蛋白，抗體，多肽，核酸分子，納米粒等。由于強水溶性加帶電荷，磺化花青素標記的生物分子更穩定，不易產生疏水性聚集。

本產品磺化Cy7.5熒光基(fluorophore)是優化后的結構，多次甲基(polymethine)橋鏈經環己烯固化，熒光***產率提高了20%，從而使熒光更亮。

磺化Cy7.5-馬來酰亞胺的水溶性非常好，所以可以在水相的標記反應體系中直接使用，不需要有機溶劑助溶，特別適合標記對有機溶劑敏感的生物分子。另外磺化Cy7.5水溶性很好，并且染料分子本身帶電荷，標記后不會引發目標分子疏水性聚集，提高熒光標記產物的穩定性。磺化Cy7.5-伯胺也溶于甲醇，DMSO，DMF等有機溶劑，標記反應也可以在純有機溶劑中進行。如需脂溶性Cy7.5染料，可選擇普通花青(cyanine)，即Cy7.5-馬來酰亞胺( D10039 )。

磺化Cy7.5-馬來酰亞胺標記后的產物Ex/Em是788/808nm。和它具有相似熒光特性的染料包括Alexa Fluor 790，DyLight 800，ICG等。
