Near-infrared, sulfhydryl reactive Cyanine7 dye, an analog of Cy7? maleimide._x000D_
_x000D_
This reagent allows to attach near infrared Cyanine7 dye to proteins with free sulfhydryl groups. Labeled proteins thus obtained are used in NIR bioimaging applications. NIR imaging systems can be used to visualize distribution of labeled proteins in tissues even in live organism.
