Technical Data
D2727-71
Delta-like 1 (DLL1, Delta1, DL1, H-Delta-1, UNQ146/PRO172)
Description:
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 gamme-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).

Applications:
Suitable for use in ELISA, Western Blot and Immunoprecipitation. Other applications not tested.

Recommended Dilution:
Western Blot: 1:1000
Immunoprecipitation: 1:50
Optimal dilutions to be determined by the researcher.

Storage and Stability:
For long-term storage, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
