Heterodimers between TCF3 and tissue-specific basic helix-loop-helix (bHLH) proteins play major roles in determining tissue-specific cell fate during embryogenesis, like muscle or early B-cell differentiation. Together with TCF15, required for the mesenchymal to epithelial transition. Dimers bind DNA on E-box motifs: 5'-CANNTG-3'. Binds to the kappa-E2 site in the kappa immunoglobulin gene enhancer (By similarity). Binds to IEB1 and IEB2, which are short DNA sequences in the insulin gene transcription control region. 图像 WB检测TCF3/E2A蛋白(货号 GB115489). 样品: 经RIPA裂解液(货号G2002)处理的蛋白质. 封闭: 封闭: 3%脱脂牛奶(货号GC310001)溶于TBST溶液, 室温孵育1小时. —抗: 1: 300稀释, 4℃ 孵育过夜. 二抗: HRP标记山羊抗兔IgG (H+L) (货号GB23303), 1: 5000稀释, 室温孵育1小时. 储存 储存条件 在-20℃下储存一年, 避免反复冻融. 储存缓冲液 含0.15% ProClin300防腐剂, 100 μg/mL牛血清白蛋白和50%甘油的磷酸盐缓冲液. 注意: 1.本产品仅供研究使用. 2.建议用一抗稀释液( G2025 )稀释本产品.
