sulfo-Cyanine7.5 is a near infrared fluorophore with absorption and emission ranges around 800 nm. Its spectral properties allow for the efficient leveraging of tissue NIR transparency window. The fluorophore is available as different reactive forms, this one is maleimide for the labeling of SH groups of proteins and peptides. The sulfo- version is highly hydrophilic.

Such labeled biomolecules are useful in biodistribution studies and visualization in intact organisms.

sulfo-Cyanine7.5 是一种近红外荧光团,吸收和发射范围约为 800 nm。 其光谱特性允许有效利用组织 NIR 透明度窗口。 荧光团有不同的反应形式,这是一种马来酰亚胺,用于标记蛋白质和肽的 SH 基团。 磺化剂是高度亲水的。
