| Specificity / Sensitivity | Cleaved Notch1 (V1744) (D3B8) Rabbit mAb detects endogenous levels of the Notch1 intracellular domain (NICD) only when released by cleavage between Gly1753 and Val1754 (equivalent to Gly1743/Val1744 of murine notch1). The antibody does not recognize full-length Notch1 or Notch1 cleaved at other positions. The size of the NICD varies among cell lines due to mutations in the Notch1 C-terminus (6). |
| Source / Purification | Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to the sequence at the Val1754 cleavage site in human Notch1 (equivalent to Val1744 in mouse Notch1). Western Blotting

| Background | Notch proteins (Notch1-4) are a family of transmembrane receptors that play important roles in development and the determination of cell fate (1). Mature Notch receptors are processed and assembled as heterodimeric proteins, with each dimer comprised of a large extracellular ligand-binding domain, a single-pass transmembrane domain, and a smaller cytoplasmic subunit (Notch intracellular domain, NICD) (2). Binding of Notch receptors to ligands of the Delta-Serrate-Lag2 (DSL) family triggers heterodimer dissociation, exposing the receptors to proteolytic cleavages; these result in release of the NICD, which translocates to the nucleus and activates transcription of downstream target genes (3-4). The NICD of murine Notch1 is released (activated) by cleavage between Gly1743 and Val1744 (corresponding to Gly1753/Val1754 in human Notch1) (3, 4). Mutations that result in constitutive activation of Notch1 are associated with many different cancers, including a majority of cases of T cell acute lymphoblastic leukemia (T-ALL). Activation may be due to mutations in Notch1 itself, or in components of the ubiquitin ligase complex that negatively regulates the Notch signaling pathway (5-6).

h）即可。2. 修复大法——不仅仅是「煮一煮」微波炉修复：简单易行效果好，CST 推荐使用微波炉完成修复。合适的修复液：根据抗体说明书使用合适的修复液。用柠檬酸修复后，切片需浸泡在修复液中，自然冷却；而用 EDTA 修复后，切片可直接从修复缸中取出，直接进行下一步。注：使用不同的修复方式和不同生产商的抗体检测人肺癌组织中 EGFR 的表达。第一排为 CST 的 EGF Receptor (D38B1) XP® Rabbit mAb（#4267），EDTA 的修复方式明显优于柠檬酸盐及胃蛋白
，EDTA 缓冲液适用于多数磷酸化酪氨酸特异性抗体，而柠檬酸盐缓冲液适用于其他多数抗体。每天都需制备新鲜的 1X 溶液。抗体：hospho-HER3/ErbB3 (Tyr1289) (D1B5) Rabbit mAb #2842样本：蜡包埋人类肺部肿瘤抗原修复缓冲液：柠檬酸盐缓冲液（左）或者 EDTA 缓冲液（右）煮沸装置载玻片在所推荐的缓冲液中加热煮沸一段时间后，才可引起抗原修复。该步骤通常在微波炉或高压锅中进行。虽然，一些研究人员也使用水浴锅，但是，因为该步骤中所选择的装置对染色存在积极或消极的影响
