Preparation: Produced from sera of rabbits immunized with highly pure Recombinant Human sDLL-4. Anti-Human sDLL-4-specific antibody was purified by affinity chromatography employing an immobilized Human sDLL-4 matrix. Sandwich ELISA: To detect Human sDLL-4 by sandwich ELISA (using 100 μL/well antibody solution) a concentration of 0.5-2.0 μg/mL of this antibody is required. This antigen affinity purified antibody, in conjunction with PeproTech Biotinylated Anti-Human sDLL-4 (500-P279Bt) as a detection antibody, allows the detection of at least 0.2-0.4 ng/well of Recombinant Human sDLL-4. Western Blot: To detect Human sDLL-4 by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 μg/mL. Used in conjunction with compatible secondary reagents the detection limit for Recombinant Human sDLL-4 is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions.

Delta-like ligand 4 (DLL4), also know as Delta-4, is a homologue of the Drosophila delta protein, and functions as a transmembrane bound ligand to the notch receptor Notch1. DLL4 is expressed in the vasculature and plays a critical role in vascular development. It is induced by vascular endothelial growth factor (VEGF), as a negative feedback regulator to regulate angiogenic sprouting and promote the formulation of a differentiated vascular network. DLL4 has been found to be strongly expressed in tumor vessels of clear-cell renal tumors and bladder cancer, and inhibition of DLL4 results in increased vascular proliferation but defective maturation. This in turn leads to a decrease in tumor growth, with no apparent toxicity.
