N-(1-Pyrenyl)maleimide Chemical Properties, Uses, Production
Description
Pyrene is a fluorescent hydrocarbon which emits in blue region. This is a maleimide derivative of pyrenebutyric acid which reacts with thiols.
Pyrene is a useful proximity probe because two pyrene residues close to each other exhibit strong excimer fluorescence.
Chemical Properties
N-(1-PYRENYL)MALEIMIDE is Yellow Solid
Uses
Reactant used in synthesis of: • ;Oligodeoxynucleotide derivatives1 • ;Polymer conjugates of immunogenic peptides2 • ;Modified oligonucleotides for biosensing applications3,Reactant: • ;Involved in synthesis of thermally stable fluorescent maleimide/isobutene alternating copolymers4• ;Used as derivitizing agent for determination of glutathione disulfide levels in biological samples5
Uses
N-(1-PYRENYL)MALEIMIDE is a fluorescent sulfhydryl reagent that can form excited-state dimers which emit at longer wavelenghts than the lone excited fluorophore.
Abs/Em Maxima
343; 326; 313; 276; 265; 242; 234/377; 397 nm
