4-戊戊酰基輔酶A(三氟乙酸鹽)產品是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.
