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+ TCF-4 set includes the TCF-4 antibody, a negative control normal mouse IgG, and qPCR primers which amplify a 198 bp region of human SP5 promoter. The TCF-4 and negative controls are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of TCF-4-associated chromatin. View All» Specificity: This antibody recognizes TCF-4 View All» Molecular Weight: ~66 kDa View All» Immunogen: Amino acids 31-331 of human TCF-4. View All» Isotype: IgG2a View All» Background Information: TCF4, also known as TCF7L2, is expressed widely during development. Gene targeting study indicates that it is required to maintain the crypt stem cells of the small intestine. TCF4 has many different splicing isoforms and they are expressed differentially in tissues and in cancers of different stages. Studies also indicate that variant of the TCF4 gene confers an increased risk of type 2 diabetes. View All» Species Reactivity:

Successful immunoprecipitation of TCF-4 associated DNA fragments was verified by qPCR using ChIP Primers, SP5 Promotor as a positive locus, and GAPDH 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™ G (Cat. # 17-409) or EZ-ChIP™ (Cat. # 17-371) protocol for experimental details.Western Blot Analysis: Representative lot data.Cos-1 cells were transfected with TCF-4 cDNA in pUSE (lane 2) or pUSE (lane 1). RIPA lysates were prepared, resolved by electrophoresis, transferred to nitrocellulose and probed with anti-TCF-4 (1 mg/mL).Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP and a chemiluminescence detection system.Arrow indicates TCF-4 (~66 kDa) (Please see figures).Immunocytochemistry/Immunohistochemistry:A previous lot of this antibody is reported to show positive immunostaining for TCF-4 in cells fixed with 4% paraformaldehyde/PBS (Amir, A. L., 2003).Immunoprecipitation: A previous lot of this antibody was reported to immunoprecipitate TCF-4 from SW620 whole cell lysate as a complex with Beta-Catenin (Persad, S., 2001).Supershift Assay (EMSA): A previous lot of this antibody was reported to supershift TCF-4/DNA complexes in electrophoretic mobility shift assays (EMSA) (Amir, A. L., 2003). View All» Control: Includes negative control normal mouse IgG and primers specific for human SP5 promoter.

        View All» Entrez Gene Summary: SOX-TCF_HMG-box, class I member of the HMG-box superfamily of DNA-binding proteins. These proteins contain a single HMG box, and bind the minor groove of DNA in a highly sequence-specific manner. Members include SRY and its homologs in insects and vertebrates, and transcription factor-like proteins, TCF-1, -3, -4, and LEF-1. They appear to bind the minor groove of the A/T C A A A G/C-motif. View All» UniProt Summary: FUNCTION: Participates in the Wnt signaling pathway and modulates MYC expression by binding to its promoter in a sequence-specific manner. Acts as repressor in the absence of CTNNB1, and as activator in its presence. Activates transcription from promoters with several copies of the Tcf motif CCTTTGATC in the presence of CTNNB1. TLE1, TLE2, TLE3 and TLE4 repress transactivation mediated by TCF7L2 and CTNNB1. Expression of dominant-negative mutants results in cell-cycle arrest in G1 (By similarity). Necessary for the maintenance of the epithelial stem-cell compartment of the small intestine.SIZE: 619 amino acids; 67919 Da SUBUNIT: Interacts with TGFB1I1. Interacts with CTNNB1 (via the armadillo repeat); forms stable transcription complex. Interacts with EP300 (By similarity).SUBCELLULAR LOCATION: Nucleus. Note=Diffuse pattern. Colocalizes with SUMO1 and PIAS4 in a subset of PML (promyelocytic leukemia) nuclear bodies (By similarity).TISSUE SPECIFICITY: Detected in epithelium from small intestine, with the highest expression at the top of the crypts and a gradient of expression from crypt to villus. Detected in colon epithelium and colon cancer, and in epithelium from mammary gland and carcinomas derived therefrom.DISEASE: Constitutive activation and subsequent transactivation of target genes may lead to the maintenance of stem-cell characteristics (cycling and longevity) in cells that should normally undergo terminal differentiation and constitute the primary transforming event in colorectal cancer (CRC).SIMILARITY: Contains 1 HMG box DNA-binding domain.
