Description

General description

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+ Ubiquityl-Histone H2B, (clone 56) set includes the Ubiquityl-Histone H2B, (clone 56) antibody, a negative control antibody (purified Mouse IgG), and qPCR primers which amplify a 213 bp region within the coding region of the human GAPDH gene.
The ubiquityl-Histone H2B and negative control antibodies are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of Ubiquityl-Histone H2B associated chromatin.

Specificity

Not tested in other species. The immunogen sequence is identical in a wide range of animal and plant species, so broad cross-reactivity is expected.

Recognizes histone H2B ubiquitinated on lysine 120 but not free ubiquitin or histone H2B in its unmodified state.

Immunogen

Epitope: Lys120 ubiquitination site

Immunogen used was a branched peptide corresponding to the ubiquitination site on human histone H2B.

Application

Chromatin Immunoprecipitation:
Sonicated chromatin prepared from HeLa S3 cells (1 X 10⁶ cell equivalents per IP) was subjected to chromatin immunoprecipitation using 1 μg of either a normal mouse IgG or Anti-Ubiquityl-Histone H2B antibody and the Magna ChIP G Kit (Cat. # 17-611).
Successful immunoprecipitation of ubiquityl-Histone H2B associated DNA fragments was verified by qPCR using GAPDH promoter (negative) and GAPDH coding (positive) Primers (Please see figures). 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 G ChIP (Cat. # 17-409) or EZ-ChIP (Cat. # 17-371) protocol for experimental details.

Western Blot Analysis:
HeLa cell lysate was resolved by electrophoresis, transferred to PVDF and probed with anti-Ubiquityl-histone H2B at a dilution of 1:4000 (Please see figures).

Quality

Chromatin Immunoprecipitation:
Sonicated chromatin prepared from HeLa S3 cells (1X 10⁶ cell equivalents per IP) were subjected to chromatin immuno-precipitation using 1 µg of either a normal mouse IgG or Anti-ubiquityl-Histone H2B, clone 56 antibody and the Magna ChIP^® G Kit (Cat. # 17-611). Successful immunoprecipitation of ubiquityl-Histone H2B-associated DNA fragments was verified by qPCR using Control Primers.
