Protocols

Specificity / Sensitivity

Notch1 (C37C7) 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 Gln2497 of human Notch1.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using Notch1 (C37C7) Rabbit mAb.

Chromatin IP

Chromatin IP

CUTLL1 cells were cultured in media with γ-secretase inhibitor (1 μM) for 3 days and then either harvested immediately (left panel) or washed and cultured in fresh media for 3 h (right panel). Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 cells and 10 µl of Notch1 (C37C7) 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.

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).
