Protocols

Specificity / Sensitivity

Notch2 (D67C8) XP® Rabbit mAb detects endogenous levels of total Notch2 protein. It recognizes both the full-length (~ 300 kDa) and the transmembrane/intracellular region NTM (~110 kDa).

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding residues surrounding Val2332 of human Notch2.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using Notch2 (D67C8) XP® Rabbit mAb. The full-length (FL) Notch2 protein and the transmembrane/intracellular region (NTM) are indicated.

IF-IC

IF-IC

Confocal immunofluorescent analysis of 293 cells using Notch2 (D67C8) XP® Rabbit mAb (green). Blue pseudocolor = DRAQ5® #4084 (Fluorescent DNA dye).

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).

Notch2 is a member of Notch family and mutation in Notch2 is associated with Alagille syndrome (5).
