Acetyl-Lysine Affinity Beads - AAC03
Acetyl-Lysine Affinity Beads
Cytoskeleton offers two types of Acetyl-Lysine Affinity Beads, Cat # AAC02-Beads and Cat # AAC03-Beads. Both reagents are comprised of mouse anti-acetyl-lysine antibodies that are covalently linked to protein G beads and both enrich a broad range of acetylated proteins. AAC02-Beads and AAC03-Beads can be combined to give a more extensive acetylated protein enrichment profile (Cat # AAC04-Beads is a 1:1 combination of AAC02-Beads:AAC03-Beads).
AAC03-Beads has an overlapping but unique specificity profile when compared to AAC02-Beads and may outperform AAC02-Beads when examining a specific target protein, see Detailed methods and Validated Applications for examples. As acetylation generally represents a very small percent of total target protein, utilizing optimized reagents is extremely critical to success. When examining the acetylation state of a new protein of interest (POI), it is recommended to try AAC03-Beads and AAC02-Beads separately to determine which reagent is optimal for your POI.
Each lot of affinity-bead is quality controlled to provide high batch to batch consistency, see COA documents.
Validated Applications
Application 1: Detection of Acetylation Changes in a Target POI
AAC03-Beads have been shown to be a superior reagent for the immunoprecipitation of acetylated EGFR and RhoGDI Target POI (Fig. 1). In the presence of HDAC inhibitors AAC03-Bead IPs show a an 11.3 fold and a 2.5 fold enhanced acetylation of EGFR and RhoGDI respectively. While AAC02-Bead shows a weaker 8 fold and 1.1 fold increase respectively.
Figure 1 Legend: AAC03-Beads & AAC02-Beads (50µl bead slurry) and a 1:1 mix (25 µl each) AAC04-Beads, were used to IP acetylated proteins from Cos-7 cells either treated (+) or untreated (-) with deacetylase inhibitors, [TSA (1µM) and nicotinamide (1mM)], for 6 hours. Western blot analysis using anti EGFR and anti -RhoGDI antibodies was performed and signals were quantitated using LiCor Empiria software. IP assays were also carried out and signals quantitated for mouse IgG control beads (blots not shown). Each IP used 1 mg of lysate.
Application 2: Immunoprecipitation of Total Acetyl-Lysine Profile
AAC03-Beads show a robust total acetyl IP profile with an overlapping but unique specificity profile to AAC02-Beads. AAC03-Beads can be used alone or in combination with AAC02-Beads to study the acetylome.
Figure 2 Legend: AAC02-Beads, AAC03-Beads, and AAC04-Beads (50µl bead slurry) were used to IP acetylated proteins from Cos-7 cells either treated (+) or untreated (-) with deacetylase inhibitors [TSA (1µM) and nicotinamide (1mM)] for 6 hours. The total profile of enriched acetylated proteins were eluted and analyzed by western blot with an AAC03-HRP antibody (1:3000). Mouse IgG beads are used as a control for non-specific binding (Cat # CIG02). Each IP assay utilized 1 mg of Cos-7 lysate
