Sulfo-Cyanine7 maleimide,马来酰亚胺水溶近红外性荧光染料
A reactive dye with a
maleimide group for the labeling of thiol groups of proteins and other
biomolecules, an analog of Cy7® maleimide.
Sulfo-Cyanine7 is a near
infrared fluorophore which is hydrophilic and contains a rigidizing ring in its
heptamethine chain that improves its photophysical properties. A great dye for
various applications, including NIR imaging.
