  • Applications
  • ChIP
  • ChIP
  • ChIP assays were performed using human osteosarcoma (U2OS) cells. A titration of the antibody consisting of 2, 5, 10 or 15 ul per ChIP experiment was analysed. IgG (5 ug/IP) was used as negative IP control. Quantitative PCR was performed with primers for the promoter of the ALDOA gene and for the coding region of the myogenic differentiation gene (MYOD), a gene that is inactive at normal conditions. The figure shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis). These results are in accordance with the observation that dimethylation of K4 at histone H3 is more present at active genes than at silent genes.
  • Western Blot (Cell lysate)
  • Western Blot (Cell lysate)
  • Western Blot (Cell lysate) analysis of 15 ug histone extracts of HeLa cells.
  • ELISA
  • ELISA
  • ELISA is a quantitative method used to determine the titer of the antibody using a serial dilution of antibody against Histone H3 (K4me2). 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 1:2600.
  • Dot Blot
  • Dot Blot
  • Cross reactivity test using the Histone H3 (K4me2) antibody.
    Dot Blot analysis was performed with peptides containing other modifications or unmodified sequences of histone H3. Other histone modifications include monomethylation and trimethylation of the same lysine and monomethylation, dimethylation and trimethylation of lysine 9, 27 and 36 and 79. One hundred to 0.2 pmol of the peptides were spotted on a membrane. The antibody was used at a dilution of 1:20000. The figure shows a high specificity of the antibody for the modification of interest.

  • Gene Information
  • Entrez GeneID:
  • 8350
  • Gene Name:
  • HIST1H3A
  • Gene Alias:
  • H3/A,H3FA
  • Gene Description:
  • histone cluster 1, H3a
  • Gene Summary:
  • Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. This structure consists of approximately 146 bp of DNA wrapped around a nucleosome, an octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. This gene is intronless and encodes a member of the histone H3 family. Transcripts from this gene lack polyA tails; instead, they contain a palindromic termination element. This gene is found in the large histone gene cluster on chromosome 6p22-p21.3. [provided by RefSeq
