Western Blot: Histone H3 [ac Lys18, Dimethyl Arg17] Antibody [NBP2-59217]

Western Blot: Histone H3 [ac Lys18, Dimethyl Arg17] Antibody [NBP2-59217]

Western Blot: Histone H3 [ac Lys18, Dimethyl Arg17] Antibody [NBP2-59217] - Western blot was performed on whole cell (25 ug, lane 1) and histone extracts (15 ug, lane 2) from HeLa cells, and on 1 ug of recombinant histone H2A, H2B, H3 and H4 (lane 3, 4, 5 and 6, respectively) using the antibody against H3K18ac. The antibody was diluted 1:500 in TBS-Tween containing 5% skimmed milk. Observed molecular weight is ~15 kDa.
Chromatin Immunoprecipitation: Histone H3 [ac Lys18, Dimethyl Arg17] Antibody [NBP2-59217] - ChIP assays were performed using human HeLa cells, treated with TSA, the antibody against H3K18ac and optimized PCR primer pairs for qPCR. ChIP was performed using sheared chromatin from 1,000,000 cells. A titration consisting of 1, 2, 5 and 10 ug of antibody per ChIP experiment was analyzed. IgG (2 ug/IP) was used as a negative IP control. Quantitative PCR was performed with primers for the promoters of the active EIF4A2 and c-fos genes, used as positive controls, and for the inactive MYOD1 gene and the Sat2 satellite repeat, used as negative controls. Figure shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis).

ELISA: Histone H3 [ac Lys18, Dimethyl Arg17] Antibody [NBP2-59217]

ELISA: Histone H3 [ac Lys18, Dimethyl Arg17] Antibody [NBP2-59217] - To determine the titer of the antibody, an ELISA was performed using a serial dilution of the antibody against H3K18ac. The antigen used was a peptide containing the histone modification of interest. By plotting the absorbance against the antibody dilution, the titer of the antibody was estimated to be 1:4,300.
Immunofluorescence: Histone H3 [ac Lys18, Dimethyl Arg17] Antibody [NBP2-59217]

Immunofluorescence: Histone H3 [ac Lys18, Dimethyl Arg17] Antibody [NBP2-59217]

Immunofluorescence: Histone H3 [ac Lys18, Dimethyl Arg17] Antibody [NBP2-59217] - HeLa cells were stained with the antibody against H3K18ac and with DAPI. Cells were fixed with 4% formaldehyde for 10' and blocked with PBS/TX-100 containing 5% normal goat serum and 1% BSA. The cells were immunofluorescently labeled with the H3K18ac antibody (left) diluted 1:200 in blocking solution followed by an anti-rabbit antibody conjugated to Alexa Fluor 488. The middle panel shows staining of the nuclei with DAPI. A merge of the two stainings is shown on the right.

Background: Histone H3

Chromatin is an arrangement of DNA and proteins which form chromosomes. Chromatin is formed from nucleosomes, which are comprised of a set of four histone proteins (H2A, H2B, H3, H4) wrapped with DNA. Chromatin is very dynamic, where post-translational modifications can regulate DNA to be copied, transcribed, or repaired.

Histones are nuclear proteins responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Changes in chromatin structure play a large role in the regulation of transcription. The chromatin fibers are compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures.

Common histone modifications include methylation of lysine and arginine, acetylation of lysine, phosphorylation of threonine and serine, and sumoylation, biotinylation, and ubiquitylation of lysine. Posttranslational modifications such as acetylation of core histones regulates gene expression, thus altering protein function and regulation (1). Histone H3 is primarily acetylated at lysines 9, 14, 18, and 23 and have a theoretical molecular weight of 15 kDa. Acetylation at lysine 9 and 14 appears to control histone deposition, chromatin assembly and active transcription. Methylation of arginine residues within histone H3 has also been linked to transcription regulation. Histone H3 has been linked to various types of cancer as a biomarker through the aberrant expression of histone deacetylase (HDAC) enzymes and changes to chromatins (2-4).
