ChIPAb+ Histone H3.3 - ChIP Validated Antibody and Primer Set

All 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+ Histone H3.3 set includes the Histone H3.3 antibody, a Normal rabbit IgG, and control primers which amplify a 87 bp region of ChIP Primers, GAPDH Coding Region D2 Human. The Histone H3.3 and negative controls are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of Histone H3.3 -associated chromatin.

Broad species cross-reactivity expected based on 100% sequence homology.

This antibody recognizes human Histone H3.

Epitope: a.a. 85-105

KLH-conjugated linear peptide corresponding to human Histone H3.3.

Chromatin Immunoprecipitation:
Representative lot data.
Sonicated chromatin prepared from HeLa cells (1 X 10E6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 2 µg of either Normal rabbit IgG or 2 µg Anti-Histone H3.3 and the Magna ChIP A Kit (Cat. # 17-610). Successful immunoprecipitation of Histone H3.3 associated DNA fragments was verified by qPCR using ChIP Primers, GAPDH Coding Region D2 as a positive locus, and beta-actin promoter primers as a negative locus. (Figure 2). Data is presented as percent input of each IP sample relative to input chromatin for each amplicon and ChIP sample as indicated.
Please refer to the EZ-Magna ChIP A (Cat. # 17-408) or EZ-ChIP (Cat. # 17-371) protocol for experimental details.
Western Blot Analysis:
Representative lot data.
HeLa acid extract was probed with Anti-Histone H3.3 (1 µg/mL). Proteins were visualized using a Donkey Anti-Rabbit IgG secondary antibody conjugated to HRP and a chemiluminescence detection system.
Arrow indicates Histone H3.3 (~17 kDa). (Figure 3).

Chromatin Immunoprecipitation:
Representative lot data.
Sonicated chromatin prepared from HeLa cells (1 X 10E6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 2 µg of either Normal Rabbit IgG or 2 µg of Anti-Histone H3.3 and the Magna ChIP^® A Kit (Cat. # 17-610).

Stable for 1 year at -20°C from date of receipt. Handling Recommendations: Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
Note: Variability in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.

Control
Includes normal rabbit IgG and primers specific for human GAPDH coding region.

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
