5MP-Propargyl
5MP-Propargyl is the derivative of 5-Methylene pyrrolone (5MP). 5-Methylene pyrrolones (5MPs) are thiol-specific, reversible bioconjugation reagents for cysteine-specific protein modification, that are commonly used for protein bioconjugation. 5MP-Propargyl is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
