TCF4 encodes transcription factor 4, a basic helix-turn-helix transcription factor. The protein recognizes an Ephrussi-box ('E-box') binding site ('CANNTG') - a motif first identified in immunoglobulin enhancers. TCF4 is expressed predominantly in pre-B-cells, although it is found in other tissues as well.
TCF4 antibody can be used for detection of TCF4 by ELISA at 1:62500. TCF4 antibody can be used for detection of TCF4 by western blot at 1.0 μg/mL, and HRP conjugated secondary antibody should be diluted 1:50,000 - 100,000.
