Detection of Human TCF7/TCF1 by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line and MOLT-4 human acute lymphoblastic leukemia cell line. PVDF membrane was probed with 0.2 µg/mL of Goat Anti-Human TCF7/TCF1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5596) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). Specific bands were detected for TCF7/TCF1 at approximately 60, 40, and 38 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

TCF7/TCF1 in HCT‑116 Human Cell Line. TCF7/TCF1 was detected in immersion fixed HCT-116 human colorectal carcinoma cell line using Human TCF7/TCF1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5596) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red, upper panel; Catalog # NL001) and counterstained with DAPI (blue, lower panel). Specific staining was localized to nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

TCF7/TCF1 in Human Thymus. TCF7/TCF1 was detected in immersion fixed paraffin-embedded sections of human thymus using Goat Anti-Human TCF7/TCF1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5596) at 3 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to nuclei.

Background: TCF7/TCF1

TCF7 (Transcription factor 7; also T cell factor 1/TCF1) is a 25‑50 kDa member of the lymphoid enhancer binding factor family of proteins with 16 isoforms. It is expressed in thymocytes and mature T cells, and serves multiple purposes. In resting cells, TCF family members are transcriptional repressors, and are 25‑32 kDa in size. Following activation, large TCF7 isoforms predominate (42‑50 kDa), and serve a transcriptional activator function. Human TCF7 is 384 amino acids (aa) in length. This is likely an activating isoform that contains a beta -catenin binding domain (aa 1‑59), a DNA-binding HMG-box (aa 269‑337), and an NLS (aa 344‑348). The use of an alternate start site at Met116 seems to characterize repressor isoforms.
