Lymphoid Enhancing Factor 1 (LEF1) is a transcription factor belonging to the TCF/LEF family. LEF1 was first identified as a protein binding to TCR-α enhancer and upregulates expression of T-cell antigen receptor α chain. LEF1 is involved in Wnt signaling pathways as a ubiquitous regulator. During Wnt signaling, translocation of β-catenin from the cytosol to the nucleus results in elevation of transcriptional activity of LEF1, which subsequently regulates multiple downstream genes.Product Details

- Recommended Usage
Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 1.0 µg per ml. For immunocytochemistry, a concentration of 5.0 μg/ml is recommended. For immunoprecipitation, the suggested use of this reagent is 2.5 µg per ml. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
W17155A recognizes multiple isoforms of LEF1.
When tested for ICC, W17155A failed to stain PFA-fixed Jurkat cells permeabilized with methanol. We recommend Triton X-100 permeabilization.
- LEF1 is a 399 amino acid protein with a predicted molecular weight of 44 kD. Seven total isoforms have been reported, ranging in size from 23 to 44 kD.
