4-戊戊酰基辅酶A(三氟乙酸盐)产品是4-pentynoyl-Coenzyme A (trifluoroacetate salt) is an alkyne-derivatized acetyl-CoA reporter. It is metabolically transferred onto lysine residues of proteins by lysine acetyltransferases. It enables rapid detection and identification of acetylated proteins in vitro and in mammalian cells through Cu(I)-catalyzed azide-alkyne cycloaddition.
