FITC-Cysteine（Cys）

FITC-Cysteine（Cys),Fluorescein-Cysteine from ruixi.Fluorescein cystein is a fluorescein labeled cysteine.The compounds on which fluorescent labeling depends are called fluorescent substances.Fluorescent substances refer to compounds with conjugated double bond system.When irradiated by ultraviolet light or blue violet light,they can be excited into excited states.When they recover from the excited state to the ground state,they emit fluorescence.
