The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 0.125 µg/ml. Detects a band of approximately 49 kDa (predicted molecular weight: 42 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
Use a concentration of 4 - 8 µg/ml.
功能Transcriptional activator involved in T-cell lymphocyte differentiation. Necessary for the survival of CD4(+) CD8(+) immature thymocytes. Isoforms lacking the N-terminal CTNNB1 binding domain cannot fulfill this role. Binds to the T-lymphocyte-specific enhancer element (5'-WWCAAAG-3') found in the promoter of the CD3E gene. May also act as feedback transcriptional repressor of CTNNB1 and TCF7L2 target genes. TLE1, TLE2, TLE3 and TLE4 repress transactivation mediated by TCF7 and CTNNB1.
组织特异性Predominantly in T-cells. Also detected in proliferating intestinal epithelial cells and in the basal epithelial cells of mammary gland epithelium.
序列相似性Belongs to the TCF/LEF family. Contains 1 HMG box DNA-binding domain.
Immunohistochemistry (Formalin/PFA-fixed parraffin-embedded sections) analysis of human kidney tissue labelling Transcription factor 7 with ab30961 at 4-8µg/ml. Positively labelled cells (epithelial cells of renal tubule) are indicated by arrows. Magnification: 400X.
