| 反应种属 | Human |
| 应用 | Western Blot(0.1 µg/mL) |
| 目标/特异性 | Detects human Notch-3 in direct ELISAs and Western blots. In direct ELISAs, approximately 50% cross-reactivity with recombinant mouse Notch-3 is observed and less than 5% cross-reactivity with recombinant human (rh) Notch-1 and rhNotch-2 is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL Blockade of Receptor-ligand Interaction: In a functional ELISA, 1-3 µg/mL of this antibody will block 50% of the binding of 250 ng/mL of Recombinant Rat Jagged 1 Fc Chimera (Catalog # 599-JG) to immobilized Recombinant Human Notch-3 Fc Chimera (Catalog # 1559-NT) coated at 5 µg/mL (100 µL/well). At 10 μg/mL, this antibody will block >90% of the binding. |

| 背景 | Human Notch-3 is part of the Notch family of type I transmembrane glycoproteins involved in a number of early-event developmental processes (1). The extracellular domain of Notch receptors interact with the extracellular domain of transmembrane ligands Jagged, Delta, and Serrate expressed on the surface of a neighboring cell. In both vertebrates and invertebrates, Notch signaling is important for specifying cell fates and for defining boundaries between different cell types. The Notch molecule is synthesized as a 2321amino acid (aa) precursor that contains an 39 aa signal sequence, a 1603 aa extracellular region, a 21aa transmembrane (TM) segment and a 658 aa cytoplasmic domain. The large Notch extracellular domain has 34 EGF-like repeats followed by three notch/Lin-12 repeats (LNR) (2). The 11th and 12th EGF-like repeats of Notch have been shown to be both necessary and sufficient for binding the ligands Serrate and Delta, in Drosophila (3). Notch-3 has the same biochemical mechanism of signal tranduction as Notch-1, where a series of cleavage events result in the release of the Notch intracellular domain (NICD). NICD translocates into the nucleus and initiates transcription of Notch-responsive genes (4). Thus, Notch acts as both a ligand-binding receptor and a nuclear factor that regulates transcription. Mutations in Notch-3 in humans cause an autosomal dominant condition called CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy). This disorder is characterized by recurrent ischemic strokes at an early age without any underlying vascular risk and progressive dementia. Nearly all mutations leading to this disorder are clustered in the first 5 EGF repeats of the Notch-3 gene (5). Human Notch-3 shows 90% aa identity to mouse Notch-3 over the entire protein. |
