Powered by BiozThis antibody meets EpiCypher’s “SNAP-ChIP® Certified” criteria for specificity and efficient target enrichment in a ChIP experiment (<20% cross-reactivity across the panel, >5% recovery of target input) based on technology originating from Grzybowski et al. [1] and profiling standards from Shah et al. [2]. This antibody reacts to H3K18 acetylation as well as extended acyl states (butyrylation, bu; crotonylation, cr) when present alone and in combination (H3K4,9,14,18ac). No cross reactivity to other lysine acylations in the EpiCypher SNAP-ChIP KAcylStat panel (EpiCypher 19-3001) is detected.
Figure 1: SNAP-ChIP-qPCR
Histone H3K18acyl antibody (3 µg) was tested in a native ChIP experiment using chromatin from K-562 cells (3 µg) with the SNAP-ChIP K-AcylStat Panel spiked-in prior to micrococcal nuclease digestion. Specificity (left y-axis) was determined by qPCR for the DNA barcodes corresponding to modified nucleosomes in the SNAP-ChIP panel (x-axis). Black bar represents antibody efficiency (right y-axis; log scale) and indicates percentage of the target immunoprecipitated relative to input.
Figure 2: Western Blot Data
Western analysis of H3K18acyl from 30 μg of HeLa whole cell lysate after 0.012% DMSO (Lane A) or 0.4 μM Trichostatin A (Lane B) treatment for 18 hours. H3K18acyl antibody was used for detection at 1:5,000 dilution.

Left Panel: Detection of H3K18acyl (green) using H3K18acyl antibody at a 1:500 dilution and a fluorescently labeled anti-rabbit IgG secondary antibody. Middle Panel: Localization of alpha Tubulin (red). Right Panel: A merged image of the Left and Middle panels with Hoechst dye (blue) indicating nuclear localization of H3K18acyl.

Figure 5: Immunoprecipitation
IP analysis of H3K18acyl in HeLa whole cell lysate treated with 0.4 µM Trichostatin A for 18 hours. Lane A: 30 µg of HeLa whole cell lysate. Lane B: IP with control rabbit IgG antibody. Lane C: Protein recovered from IP with H3K18acyl antibody (1:400 dilution). Western analysis was performed by binding with H3K18acyl primary antibody (1:5,000 dilution), followed by detection with an HRP-conjugated anti-rabbit IgG secondary antibody.
