ChIP
ChIP assays were performed using human HeLa 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 GAPDH and c-fos genes, used as negative controls, and for the inactive MYT1 and TSH2B genes, used as a positive controls. The figure shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis).
Western Blot (Cell lysate)
Western Blot (Cell lysate) analysis of (1) 25 ug whole cell extracts of HeLa cells, (2) 1 ug of recombinant histone H2A, (3) 1 ug of recombinant histone H2B, (4) 1 ug of recombinant histone H3, and (5) 1 ug of recombinant histone H4.
Enzyme-linked Immunoabsorbent Assay
ELISA is a quantitative method used to determine the titer of the antibody using a serial dilution of antibody against Histone H2A (K119ub). 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 1:23000.
Dot Blot
Cross reactivity tests using the Histone H2A (K119ub) antibody.
Dot Blot analysis was performed with peptides containing other histone ubiquitinylations and unmodified sequences. One hundred to 0.2 pmol of the respective peptides were spotted on a membrane. The antibody was used at a dilution of 1:20000 and shows a high specificity of the antibody for the modification of interest.

HyperlinkGene 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
