Species cross-reactivity is determined by western blot using the unconjugated antibody.
Applications Key: F=Flow Cytometry
Specificity / Sensitivity
TCF1 (C63D9) Rabbit mAb (Alexa Fluor® 647 Conjugate) detects endogenous levels of total TCF1 protein. This antibody does not recognize the dominant negative isoforms of TCF1 lacking the amino-terminal β-catenin binding domain and does not cross-react with LEF1.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to a region surrounding Pro95 of human TCF1 protein.
This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 647 fluorescent dye and tested in-house for direct flow cytometry analysis in human cells. The antibody is expected to exhibit the same species cross-reactivity as the unconjugated TCF1 (C63D9) Rabbit mAb #2203.
LEF1 and TCF are members of the high mobility group (HMG) DNA binding protein family of transcription factors that consists of the following: Lymphoid Enhancer Factor 1 (LEF1), T Cell Factor 1 (TCF1), TCF3, and TCF4 (1). LEF1 and TCF1 were originally identified as important factors regulating early lymphoid development (2) and act downstream in Wnt signaling. LEF1 and TCF bind to Wnt response elements to provide docking sites for β-catenin, which translocates to the nucleus to promote the transcription of target genes upon activation of Wnt signaling (3). LEF1 and TCF are dynamically expressed during development and aberrant activation of the Wnt signaling pathway is involved in many types of cancers including colon cancer (4,5).
