ChIPAb+ NFκB p65 (RelA)-ChIP Validated Antibody and Primer Set

产品说明

一般描述

The transcription factor NFkappaB (Nuclear Factor kappa B) is involved in the expression and regulation of a number of important cellular and physiological processes such as growth, development, apoptosis, immune and inflammatory response, and activation of various viral promoters including human immunodeficiency virus long terminal repeats. NFkappaB represents a group of structurally related and evolutionarily conserved proteins related to the proto-oncogene c-Rel with five members in mammals that include Rel (cRel), RelA (p65), RelB, NFkappaB1 (p50 and its precursor p105), and NFkappaB2 (p52 and its precursor p100). NFkappaB/Rel proteins exist as homo- or heterodimers to form transcriptionally competent or repressive complexes. Although most NFkappaB dimers are activators of transcription, the p50/50 and p52/52 homodimers can repress the transcription of their target genes. The p50/p65 heterodimer of NFkappaB is the most abundant in cells.
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+ NFκB p65 (RelA) set includes the NFκB p65 (RelA) antibody, a negative control normal mouse IgG, and qPCR primers which amplify a 299 bp region of human IκBα promoter. The NFκB p65 (RelA) and negative controls are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of NFκB p65 (RelA)-associated chromatin.

特异性

This antibody recognizes an epitope overlapping the nuclear location signal (NLS) of the p65 subunit of the NFkB heterodimer. Thus it selectively binds to the activated form of NFkB.

免疫原

Epitope: NLS of p65 subunit
Peptide corresponding to human p65 coupled to BSA.

This ChIPAb+ NFκB p65 (RelA) -ChIP Validated Antibody & Primer Set conveniently includes the antibody & the specific control PCR primers.
Chromatin Immunoprecipitation:
Representative lot data.
Sonicated chromatin prepared from serum starved, TNFα-treated (20 ng/mL, 30 min) 293 cells (~3 X 10E6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 4 µg of Normal Mouse IgG or 4 µg of Anti-NFκB p65 (RelA) and the Magna ChIP A Kit (Cat. # 17-610).
Successful immunoprecipitation of NFκB p65 (RelA) associated DNA fragments was verified by qPCR using ChIP Primers, IĸBα promoter as a positive locus, and β-Actin promoter primers as a negative locus (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 ChIP A (Cat. # 17-409) or EZ-ChIP (Cat. # 17-371) protocol for experimental details.


Western Blot Analysis:
Representative lot data.
Huvec lysate (Lane 1), L6 lysate (Lane 2) and PC12 lysate (Lane 3) were resolved by electrophoresis, transferred to PVDF membrane and probed with anti-NFκB p65 (RelA) (1:500 dilution).
Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP and a chemiluminescence detection
system.
Arrows indicates protein NFκB p65 (RelA) (~65 kDa) (Please see figures).
A non-specific band may be seen at ~230 kDa in L6 lysate.

Immunofluorescence: A 1-10 μg/mL concentration of a previous lot was used in immunofluorescence.

Immunohistochemistry (paraffin sections): A 5-10 μg/mL (APAAP)
concentration of a previous lot was used in immunohistochemistry.

Immunohistochemistry (frozen sections): A 5-10 μg/mL (APAAP)
concentration of a previous lot was used in immunohistochemistry.

Electrophoretic Mobility Shift Assay (EMSA): A 0.5-1 μg/mL concentration of a previous lot was used in shift assay.

Flow Cytometry: A previous lot of this antibody was used in flow cytometry.

Optimal working dilutions must be determined by end user.
