Cyanine7.5 is a NIR dye with very long-wave emission. This product is amine-reactive derivative of this fluorophore.
Near infrared radiation readily penetrates tissues and can be used for imaging applications in vivo.
This product can be used for the labeling of various biomolecules containing amine groups, such as proteins and peptides, to track their distribution in organism in vivo by NIR imaging.
Increased rigidity of central polymethyne moiety allows to increase quantum yield by 20% compared to parent structure of Cy7.5® NHS.
Cyanine7.5 是一种具有非常长波发射的 NIR 染料。 该产品是该荧光团的胺反应性衍生物。
近红外辐射很容易穿透组织，可用于体内成像应用。
该产品可用于标记各种含胺基的生物分子，如蛋白质和多肽，通过近红外成像追踪它们在体内的分布。
与 Cy7.5® NHS 的母体结构相比，中心聚甲炔部分的刚性增加允许将量子产率提高 20%。
