  • Validation Data

    CBFb Antibody ChIP Grade

    Figure 1. ChIP results obtained with the Diagenode antibody directed against CBFb
    ChIP assays were performed using SKNO-1 cells, the Diagenode antibody against CBFb (Cat. No. C15310002) and optimized primer pairs for qPCR. Sheared chromatin from 1.25 million cells and 4 μl of antibody were used per ChIP experiment. QPCR was performed using primers specific for the FUT7, OGG1, NFE2, and SPI1 genes. Figure 1 shows the relative occupancy, calculated as the ratio + control/background for which the MYOG gene was used.

    CBFb Antibody validated in ChIP-seq

    Figure 2. ChIP-seq results obtained with the Diagenode antibody directed against CBFb
    ChIP was performed as described above. The IP’d DNA from 6 ChIP’s was pooled and analysed with an Illumina Genome Analyzer. Library preparation, cluster generation and sequencing were performed according to the manufacturer’s instructions. The 32 bp tags were aligned to the human reference genome (hg18) using the ELAND algorithm. Figure 2 shows the results of the complete chromosome 3 and three genomic regions region surrounding the OGG1, FUT7 and NFE2 genes, respectively. The position of the PCR amplicon is indicated with an arrow.

    CBFb Antibody ELISA Validation

    Figure 3. Determination of the antibody titer
    To determine the titer of the antibody, an ELISA was performed using a serial dilution of the Diagenode antibody directed against human CBFb (Cat. No. C15310002). The plates were coated with the peptides used for immunization of the rabbit. By plotting the absorbance against the antibody dilution (Figure 3), the titer of the antibody was estimated to be 1:8,800.

  • Target Description

    CBFb (UniProtKB/Swiss-Prot entry Q13951) represents the beta subunit of a heterodimeric core-binding transcription factor belonging to the PEBP2/CBF transcription factor family. These transcription factors regulate a host of genes specific to haematopoiesis (e.g. RUNX1) and osteogenesis (e.g. RUNX2). The beta subunit is the regulatory subunit which allosterically enhances the activity of the DNA binding alpha subunit as the complex binds to the core site of various enhancers and promoters. CBFb can be involved in a chromosomal rearrangement of chromosome 16 (inv(16)(p13q22)) which produces a fusion protein consisting of the N terminus of CBFb and the C-terminal portion of MYH11. This chromosomal rearrangement is associated with acute myeloid leukaemia of the M4Eo subtype.

    ERG and FLI1 binding sites demarcate targets for aberrant epigenetic regulation by AML1-ETO in acute myeloid leukemia.
    Martens JH, Mandoli A, Simmer F, Wierenga BJ, Saeed S, Singh AA, Altucci L, Vellenga E, Stunnenberg HG
    ERG and FLI1 are closely related members of the ETS family of transcription factors and have been identified as essential factors for the function and maintenance of normal hematopoietic stem cells. Here, genome-wide analysis revealed that both ERG and FLI1 occupy similar genomic regions as AML1-ETO in t(8;21) AMLs ...
