ChIP - Anti-Histone H2A.Z antibody - ChIP Grade (AB4174)

Chromatin was prepared from HeLa (Human epithelial cell line from cervix adenocarcinoma) cells according to the Abcam X-ChIP protocol.

Cells were fixed with formaldehyde for 10 min. The ChIP was performed with 25 μg of chromatin, 2 μg of ab4174 (blue), and 20 μl of Protein A/G sepharose beads. No antibody was added to the beads control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Taqman approach for active and inactive loci, Sybr green approach for heterochromatic loci). Primers and probes are located in the first kb of the transcribed region.

ChIP - Anti-Histone H2A.Z antibody - ChIP Grade (AB4174)

Changes in nucleosome occupancy upon LPS induction at a putative distal enhancer and promoter of IL1A, kinetics of nucleosome removal, and changes in histone modifications.

Chromation from mouse bone marrow derived macrophages. ChIP experiments with antibodies against H3 (dark blue bars), H2A.Z (light blue, (ab4174 at 4μg), H3K4me1 (green, ab8895 at 1 μg), H3K4me3 (yellow, ab8580 at 1 μg) and H3K27ac (red, ab4729 at 1 μg). For these experiments cross-linked chromatin was lightly digested with MNase before incubation with the respective antibodies to increase resolution of the ChIP signal and the data was normalized to a region in the ORF of RPL4. Changes upon LPS induction in histone binding and histone modifications at the enhancers and promoters of IL12B and IL1A as well as at a control region in the GAPDH pseudo gene are shown as fold over levels found before induction. For H3K27ac the changes 1.5 h after LPS induction, and for all other histone variants and modifications the changes after 3 h of induction are shown. The error bars show the SEM of at least 3 independent experiments. Statistical significance of the changes in H3K4me3 and H3K27ac upon LPS induction compared to levels found prior to induction determined by Student's T-tests is indicated (*P<0.05; **P<0.01).
