Product Pathways - Wnt / Hedgehog / Notch
DLL1 Antibody #2588
| Applications | Reactivity | Sensitivity | MW (kDa) | Source |
|---|---|---|---|---|
| W IP | R (H) | Transfected Only | 82 | Rabbit |
Applications Key:
W=Western Blotting
IP=Immunoprecipitation
Reactivity Key:
H=Human
R=Rat
Species cross-reactivity is determined by Western blot.
Specificity / Sensitivity
DLL1 Antibody detects transfected levels of DLL1. It does not recognize transfected levels of rat DLL3 and human DLL4.
Source / Purification
Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (KLH-coupled) corresponding to a region surrounding residue Ala627 of human DLL1. Antibodies are purified by protein A and peptide affinity chromatography.
Background
Notch signaling is activated upon engagement of the Notch receptor with its ligands, the DSL (Delta, Serrate, Lag2) proteins of single-pass type I membrane proteins. The DSL proteins contain multiple EGF-like repeats and a DSL domain that is required for binding to Notch (1,2). Five DSL proteins have been identified in mammals: Jagged1, Jagged2, Delta-like (DLL) 1, 3 and 4 (3). Ligand binding to the Notch receptor results in two sequential proteolytic cleavages of the receptor by the ADAM protease and the γ-secretase complex. The intracellular domain of Notch is released and then translocates to the nucleus where it activates transcription. Notch ligands may also be processed in a way similiar to Notch, suggesting a bi-directional signaling through receptor-ligand interactions (4-6).
