Product Usage Information

For optimal ChIP and ChIP-seq results, use 10 μl of antibody and 10 μg of chromatin (approximately 4 x 106 cells) per IP. This antibody has been validated using SimpleChIP® Enzymatic Chromatin IP Kits. The CUT&RUN dilution was determined using CUT&RUN Assay Kit #86652. The CUT&Tag dilution was determined using CUT&Tag Assay Kit #77552.

背景
背景
The polycomb group (PcG) of proteins contributes to the maintenance of cell identity, stem cell self-renewal, cell cycle regulation, and oncogenesis by maintaining the silenced state of genes that promote cell lineage specification, cell death, and cell-cycle arrest (1-4). PcG proteins exist in two complexes that cooperate to maintain long-term gene silencing through epigenetic chromatin modifications. The first complex, EED-EZH2, is recruited to genes by DNA-binding transcription factors and methylates histone H3 on Lys27. This histone methyl-transferase activity requires the Ezh2, Eed, and Suz12 subunits of the complex (5). Histone H3 methylation at Lys27 facilitates the recruitment of the second complex, PRC1, which ubiquitinylates histone H2A on Lys119 (6). Bmi1 is a component of the PRC1 complex, which together with Ring1 strongly enhances the E3 ubiquitin ligase activity of the Ring2 catalytic subunit (7). Bmi1 plays an important role in the regulation of cell proliferation and senescence through repression of the p16 INK4A and p19 ARF genes and is required for maintenance of adult hematopoietic and neural stem cells (3,4,8-10). 1.Boyer, L.A. et al.

CUT&Tag was performed with NCCIT cells and Bmi1 (D20B7) XP® Rabbit mAb, using CUT&Tag Assay Kit #77552. DNA library was prepared using CUT&Tag Dual Index Primers and PCR Master Mix for Illumina Systems #47415. The figures show binding across the HOXA gene cluser (upper), and the HOXD gene cluster (lower), which are known target genes of Bmi1 (see our ChIP-qPCR figure).

Chromatin immunoprecipitations were performed with cross-linked chromatin from NCCIT cells and Bmi1 (D20B7) XP® Rabbit mAb using SimpleChIP® Plus Enzymatic Chromatin IP Kit (Magnetic Beads) #9005. DNA Libraries were prepared using DNA Library Prep Kit for Illumina Systems (ChIP-seq, CUT&RUN) #56795. The figure shows binding across HoxA, a known target gene of Bmi1 (see additional figure containing ChIP-qPCR data).
