Applications

ChIP Validated ChIP-Seq Validated Western Blot Validated Immunofluorescence Validated Immunohistochemistry Validated

Application Notes

Applications Validated by Active Motif:
ChIP-Seq: 4 µg per ChIP
WB: 0.5 - 2 µg/ml

For optimal results, we recommend the addition of 0.05% Tween 20 to all blocking solutions to reduce background. Individual optimization may be required.

Immunogen

This BMI-1 antibody was raised against a recombinant protein corresponding to full-length mouse BMI-1.

Buffer

Purified IgG in 70 mM Tris (pH 8), 105 mM NaCl, 31 mM glycine, 0.07 mM EDTA, 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.

 

BMI-1 antibody (mAb) tested by ChIP-Seq.
Chromatin immunoprecipitation (ChIP) was performed using the ChIP-IT® High Sensitivity Kit (Cat. No. 53040) with 30 µg of chromatin from mouse embryonic fibroblast (MEF) cells and 4 µg BMI-1 antibody. ChIP DNA was sequenced on the Illumina NextSeq and 10 million sequence tags were mapped to identify BMI-1 binding sites.

BMI-1 antibody (mAb) tested by Western blot.
20 µg of K562 cell nuclear extract was run on SDS-PAGE and probed with BMI-1 antibody at 0.5 µg/ml. For optimal results, we recommend the addition of 0.05% Tween 20 to all blocking solutions to reduce background.

Background

BMI-1 is a member of the Polycomb PRC1 complex that is recruited to transcriptionally repressed genes subsequent to histone H3 lysine 27 methylation in order to maintain repression. In the PRC1 complex, BMI-1 is required to stimulate the E3 ubiquitin-protein ligase activity of RNF2/RING2, resulting in the ubiquitylation of histone H2A at lysine 119. BMI-1 acts as an oncogene and cooperates with c-myc in the initiation of lymphoma. High levels of expression of BMI-1 are observed in metastatic melanoma, and BMI-1 has been implicated in several other cancers. BMI-1 is required for hematopoietic stem cell self renewal.
