Signal-Seeker™ Acetyl-Lysine Detection Kit (10 assay)
![]() |
The Signal-Seeker™ line of produts have been developed to allow simple analysis of key regulatory protein modifications by specialists and non-specialists alike. The comprehensive Signal-Seeker™ kits provide an affinity bead system to isolate and enrich modified proteins from any given cell or tissue lysate. The enriched protein population is then analyzed by standard western blot procedures using a primary antibody to the target protein.
Product Uses Include
- Investigate transient regulatory mechanisms
- Measure signalling events of multiple pathway member proteins
- Discover new modifications of your protein of interest
- Gain insight into regulatory mechanisms
- Measure endogenous or transiently expressed protein signalling events

Application 1: Investigate significant Acetylation events
Immunoprecipitation using the Signal-Seeker™ Acetyl-Lysine Detection Kit compared to cell signaling acetyl lysine antibody and immunechem acetyl lysine affinity beads Figure 1. Various acetyl-lysine affinity reagents were used to IP acetylated proteins from Cos-7 cells either treated (+) or untreated (-) with TSA (1mM) and nicotinamide (1mM) for 6 hours. (1) 16.7ml of AAC04 bead slurry (20mg antibody). (2) 50ml of AAC04 bead slurry (60mg antibody). (3) Anti-acetyl lysine rabbit monoclonal mix (Cell Signaling, 1:100 per manufacturer’s instruction). (4) ImmuneChem acetyl lysine affinity bead (40mg antibody). (5) ImmunChem acetyl lysine bead (80mg antibody). (6) Normal mouse IgG control bead (60mg antibody). The total profile of enriched acetylated proteins were eluted and analyzed by western blot with an AAC03-HRP antibody (1:3000). AAC04 performed exceptionally well in enriching a broad range of acetylated proteins whereas the other commercial acetyl lysine enrichment reagents primarily enriched the most abundance acetylated proteins (e.g. acetylated tubulin and histones). |

Immunoprecipitation of target specific acetylated proteins using the Signal-Seeker™ Acetyl-Lysine Detection Kit Figure 2A: A431 cells, untreated (-) or treated (+) with 1mM TSA and 1mM nicotinamide for 6 hours, were isolated using BlastR buffer. IP was performed using AAC04 beads (60mg). Total cell lysate (Input) and immunoprecipitated samples were separated by SDS-PAGE and analyzed by western blot with antibodies against EGFR (Millipore, 1:1000), Hsp90 (Abcam, 1:20,000), P53 (Sigma, 1:2000), and RhoDGI(Millipore,1:1000) Immunoprecipitation of acetylated proteins from liver and heart tissue using the Signal-Seeker™ Acetyl-Lysine Detection Kit Figure 2B: Mouse tissue extracts (liver and heart) were obtained with BlastR buffer. IP was performed using AAC04 beads (60mg) or mIgG control bead (#CIG02, 60mg) in 1mg of tissue extracts. Enriched proteins were separated by SDS-PAGE and analyzed by western blot with AAC03-HRP (1:3000). |
