Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to
worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting
immunostaining in relation to complex human pathologies.
Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding.

TCF7L2 / TCG4 antibody was raised against his-tagged fusion protein corresponding to residues 31-331 of human TCF-4.
Recognizes human TCF-4 at 66kD in Cos-1 cells expressing transfected TCF-4. Species cross-reactivity: mouse.
Suitable for use in Western Blot, ELISA, Supershift Assay, Immunoprecipitation, Immunohistochemistry and Immunocytochemistry. Western Blot: 0.1-2 ug/ml. Detected TCF-4 in RIPA lysates of Cos-1 cells expressing transfected TCF-4. Supershift: Reported to supershift TCF-4: DNA complexes in electrophoretic mobility shift assays (EMSA). Immunoprecipitation: Reported to immunoprecipitate TCF-4 from SW620 whole cell lysates as a complex with b-Catenin. Immunocytochemistry/Immunohistochemistry: Reported to show positive immunostaining for TCF-4 in cells fixed with 4% paraformaldehyde/PBS. Positive control: DLD1 (human colorectal adenocarcinoma), Cos-1 cells or HCT116 (human colorectal carcinoma) cells.

Short term: 4°C. Long term: Store at -20°C. Avoid freeze-thaw cycles.
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 5'-CCTTTGATC-3' in the presence of CTNNB1. TLE1, TLE2, TLE3 and TLE4 repress transactivation mediated by TCF7L2/TCF4 and CTNNB1. Expression of dominant-negative mutants results in cell-cycle arrest in G1.
