| 背景 | 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. |

Immunohistochemical analysis of paraffin-embedded human breast carcinoma using Notch1 (D1E11) XP® Rabbit mAb. | |
Immunohistochemical analysis of paraffin-embedded human inflammatory granulation tissue using Notch1 (D1E11) XP® Rabbit mAb. | |
Immunohistochemical analysis of paraffin-embedded A2780 (left), Jurkat (center) and RL (right) cell pellets using Notch1 (D1E11) XP® Rabbit mAb. Both A2780 and Jurkat express Notch1, but only Jurkat cells have cleaved Notch1, while RL cells express very low or no Notch1. | |
Western blot analysis of total cell extract from various cell types using Notch1 (D1E11) XP® Rabbit mAb. The full-length (FL) Notch protein and the cleaved transmembrane/intracellular region (NTM) are indicated. | |
Western blot analysis of extracts from various cell lines using Cleaved Notch1 (Val1744) (D3B8) Rabbit mAb (upper) or Notch1 (D1E11) XP® Rabbit mAb #3608 (lower). | |

CUTLL1 cells were cultured in media with γ-secretase inhibitor (1μM) for 3 days and then either harvested immediately (left panel) or washed and cultured in fresh media for 3h (right panel). Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 cells and 2.5 µl of Cleaved Notch1 (Val1744) (D3B8) Rabbit mAb or 2 µl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using human HES1 promoter primers, SimpleChIP® Human HES4 Promoter Primers #7273, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one. | |

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 cells and 5 µl of Notch1 (D1E11) XP® Rabbit mAb or 2 µl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003.
