DescriptionChIPAb+ CBX8 - ChIP Validated Antibody and Primer Set
OverviewAll ChIPAb+ antibodies are individually validated for chromatin precipitation, every lot, every time. Each ChIPAb+ antibody set includes control primers (tested every lot by qPCR) to biologically validate your IP results in a locus-specific context. The qPCR protocol and primer sequences are provided, allowing researchers to validate ChIP protocols when using our antibody in their chromatin context. Each set also includes a negative control antibody to ensure specificity of the ChIP reaction.
The ChIPAb+ CBX8 set includes a CBX8 antibody, a Normal Rabbit IgG, and positive control primers which amplify 138 bp of the human HOXA2 promoter region. The CBX8 antibody and negative control IgG are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of CBX8 associated chromatin.

Background InformationThe family of Heterochromatin Proteins ("Chromobox Homolog", CBX) are highly conserved adapter molecules, which have important functions in the cell nucleus. These functions include gene repression by heterochromatin formation, transcriptional activation, regulation of binding of cohesion complexes to centromere, sequesteration of genes to nuclear periphery, transcriptional arrest, maintenance of heterochromatin integrity, gene repression at single nucleosome level and gene repression by heterochromatization of euchromatin.

Applications
ApplicationUse ChIPAb+ CBX8 ChIP Validated rabbit polyclonal antibody for the detection of CBX8 also known as Chromobox protein homolog 8 & Polycomb 3 homolog.
Key Applications
  • Chromatin Immunoprecipitation (ChIP)
  • Western Blotting
Application NotesChromatin Immunoprecipitation:
Sonicated chromatin prepared from Ntera-2 cells fixed for 15 min (1e6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 2 µg of either Normal Rabbit IgG (Part No. PP64B), or 2 µg Anti-CBX8 (Part No. CS207348) and the Magna ChIP™ HiSens (Cat. # 17-10460). Successful immunoprecipitation of CBX8 associated DNA fragments was verified by qPCR using ChIP Primers, HoxA2 upstream (Part No. CS203200) as a positive locus, and GAPDH promoter primers (Part No. 22-004) as a negative locus. Data are presented as percent input of each IP sample relative to input chromatin for each amplicon and ChIP sample as indicated.
Please refer to the Magna ChIP™ HiSens (Cat. # 17-10460) or EZ-MagnaChIP™ HiSens(Cat. # 17-10461) protocol for experimental details.

Chromatin Immunoprecipitation:
Sonicated chromatin prepared from Ntera-2 cells fixed for 15 min ( 1e5 and 1e6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 2 µg of either Normal Rabbit IgG (Part No. PP64B), or 2 µg Anti-CBX8 (Part No. CS207348) and the Magna ChIP™ HiSens Kit (Cat. # 17-10460). Successful immunoprecipitation of CBX8 associated DNA fragments was verified by qPCR using ChIP Primers, Hox A2 upstream (Part No. CS203200).
Please refer to the MagnaChIP™ HiSens (Cat. # 17-10460) or EZ-MagnaChIP™ HiSens (Cat. # 17-10461) protocol for experimental details.

Western Blotting Analysis: 0.1 µg/mL of this antibody detected CBX8 on 5, 15 and 50 µg of HeLa whole cell lysate and 50 µg of 293T whole cell lysate.
