AAC03-HRP, is an HRP labeled pan-acetyl lysine mouse monoclonal antibody that is part of the Signal-Seeker™ product line. AAC03-HRP anti-acetyl-lysine antibody, clone 19C4B2.1, has been tested in western blot applications and has been shown to be at least 10 times more potent than using unconjugated AAC03 with standard mouse-HRP secondary. The AAC03, anti-acetyl lysine antibody recognizes proteins post-translationally modified by acetylation on the epsilon amine groups of lysine residues that occur on 30-50% of all proteins and in particular histones, p53, tubulin and myosin. A proprietary mixture of acetylated proteins was used to produce the 19C4B2.1, highly robust antibody that has been shown to recognize a wide range of acetylated proteins. 


Validated Applications

Western Blot using Acetyl-Lysine Antibody (AAC03-HRP)

Fig 1: A: Murine tissue extract, 30 μg brain extract. B: 30 μg of Cos-7 cell lysate treated with TSA and nicotinamide (+) or untreated (-).  Strongly enhanced  bands at 55 and 14-16 kDa in TSA-treated lysate correspond to acetylated tubulin and histone proteins, respectively. C: Titration of acetylated BSA. Lanes 1-5 contain 0.5, 0.1, 0.05, 0.01, and 0.005 ng Ac-BSA, lanes 6-7 contain 500 and 1000 ng non-acetylated BSA, respectively.  AAC03-HRP was used at a 1:3000 dilution following the recommended western blot protocol.

Acetyl Lysine Western Blot

Protein Acetylation Background

Acetylation of proteins can occur as a co-translational or post-translational modification  (PTM) (1).  Co-translational acetylation occurs at the N-terminal of approximately 85% of mammalian proteins, it is irreversible and is thought to be important in protein stability, localization and synthesis (1).  Post-translational acetylation occurs on the epsilon amino group of lysine residues as a reversible and highly dynamic PTM that is known to be a key regulator in multiple cellular events, including chromatin structure, transcription,  metabolism,  signal transduction and cytoskeletal regulation (2-3).  To date over 4,000 proteins have been identified as targets for PTM acetylation which is comparable to phosphorylation in cellular prevelance (3).  Antibody AAC01 detects acetyl lysine PTMs.
