描述：

Notch1 (D1E11) XP^® Rabbit mAb 兔单抗识别内源性的总Notch1蛋白。它识别Notch1 的全长蛋白(~300 kDa)和跨膜/胞内区域NTM(~120 kDa).单抗由合成肽段免疫动物产生，相应肽段与邻近人源Notch1蛋白的Pro2438氨基酸残基序列一致。Notch1是一个在细胞发育和命运决定过程中发挥功能的跨膜蛋白（1）。在notch1成熟过程中，notch1分子细胞外结构域会被一个成对碱性氨基酸蛋白酶样的转化酶剪切（2）。在与配体如Delta1结合或是细胞外钙离子耗竭后，notch1的羧基端被释放并随后在Gly1743 和 Val1744之间被切开（3,4）。结果导致细胞内处于活化状态的notch1片段转运至细胞核内激活转录。

Specificity / Sensitivity

Notch1 (D1E11) XP^® Rabbit mAb detects endogenous levels of total Notch1 protein. It recognizes both the full-length (~300 kDa) and the transmembrane/intracellular region NTM (~120 kDa).

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro2438 of human Notch1.

Background

Notch1 is a transmembrane protein functioning in development and the determination of cell fate (1). During maturation, the notch molecule is cleaved by a furin-like convertase at its extracellular domain (2). Upon binding to a ligand such as Delta1, or upon extracellular calcium depletion, the carboxy-terminal notch1 fragment is released and further cleaved between Gly1743 and Val1744 (3,4). The resulting activated cytosolic fragment translocates to the nucleus where it activates transcription.
