ChIPAb+ CREB-ChIP Validated Antibody and Primer Set, rabbit monoclonal

32160702

Every lot of the ChIPAb+ line of antibodies is individually validated for chromatin precipitation, in order to guarantee successful ChIP assays every time. Each antibody includes a control primer set for performance confirmation. CREB antibody and the negative control antibody (rabbit normal IgG) can be used to demonstrate that the CREB antibody is functionally validated in the precipitation of CREB associated chromatin.
The qPCR primers included flank the CREB binding site in human NR4A2 promoter.
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+ CREB, antibody/primer set includes the CREB, antibody, a negative control antibody (purified rabbit IgG), and qPCR primers which amplify a 64 bp region flanking the CRE of the human cFos gene. The CREB and negative control cultured supernatant are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of CREB associated chromatin.

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 CREB, MW ~43 kDa.

CREB purified antibody is made against a KLH-conjugated synthetic peptide corre-sponding to amino acids 5-24 of human CREB.
Epitope: a.a. 5-24

This ChIPAb+ CREB -ChIP Validated Antibody & Primer Set conveniently includes the antibody & the specific control PCR primers.
Chromatin Immunoprecipitation:
Representative lot data.
Sonicated chromatin prepared from 293T cells (5 X 10⁶ cell equivalents per IP) was subjected to chromatin immunoprecipitation using 10 µL of either a negative supernatant, or CREB antibody and the Magna ChIP^® A Kit (Cat. # 17-610).
Successful immunoprecipitation of CREB-associated DNA fragments was verified by qPCR using cFos downstream 4Kb (negative) and cFos CRE (positive) (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 A ChIP (Cat. # 17-408) or EZ-ChIP (Cat. # 17-371) protocol for experimental details.

Western Blot Analysis:
Representative lot data.
HeLa nuclear extract was resolved by electrophoresis, transferred to nitrocellulose and probed with anti-CREB, clone NL904 (1:8,000 dilution)
Proteins were visualized using a goat anti-rabbit secondary antibody conjugated to HRP and a chemiluminescence detection system.
Arrow indicates CREB (~43 kDa).

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.
