Cyanine5.5 maleimide is a near-infrared fluorescent dye labeling reagent (Ex=673nm; Em=707nm). The maleimide group reacts with the SH-thiol group to form a thioether bond, thereby labeling proteins, peptides, antibodies, etc., containing cysteine molecules.
Cyanine5.5 maleimide是一种近红外荧光染料标记试剂(Ex=673nm;Em=707nm)。Maleimide基团能与SH巯基反应生成硫醚键,从而标记含半胱氨酸分子的蛋白、肽、抗体等。
