  • Applications
  • ChIP
  • ChIP
  • ChIP assays were performed using human HeLa cells. A titration of the antibody consisting of 0.5, 1, 2 and 5 ug per ChIP experiment was analysed. IgG (1 ug/IP) was used as negative IP control. QPCR was performed with primers for the coding regions of the active CCT5 and EIF2S3 genes, used as positive controls, and for the inactive TSH2B gene and the Sat2 satellite repeat region used as negative controls. The figure shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis).
  • ChIP
  • ChIP
  • ChIP assays were performed using sheared chromatin from WT yeast cells. Yeast cells with higher steady state levels of H2BK123ub and yeast cells with no ubiquitinylated H2B. Quantitative PCR was performed with primers for the coding region of an active gene. The figure shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis).
  • ChIP-Seq
  • ChIP-Seq
  • ChIP was performed with 2 ug of antibody. The figure shows the peak distribution along the complete sequence and a 3 Mb region of human chromosome 1 and in two genomic regions surrounding the CCT5 and EIF2S3 positive control genes.
  • Western Blot
