Mouse anti-Acetyl-Lysine monoclonal antibody for ELISA, WB. Acetylation of lysine is an important, reversible posttranslational modification. Lysine acetylation is a dynamic process that is used to regulate protein-DNA and protein-protein interactions . Lysine acetylation involves the reversible transfer of acetylCoA to the ?- amino group of lysine, which neutralizes its positive charge
