Sodium 4-pentynoate is a alkynylacetate analogue, can be metabolically incorporated onto cellular proteins through biosynthetic mechanisms for profiling of acetylated proteins in diverse cell types[1]. Sodium 4-pentynoate is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
Sodium 4-pentynoate (0.01-10 mM; 0.5-8 h) is used to dose- and time-dependent metabolic labeling in Jurkat T cells[1].
