Technical Data
Delta 4 (Delta-like Protein 4, DLL4, DLL-4, Delta Ligand 4 Precursor, Drosophila Delta Homolog 4, hdelta2, MGC126344, Notch Ligand DLL4 Precursor)
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 formation 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.

Suitable for use in ELISA, Immunohistochemistry and Western Blot. Other applications not tested.
