This protein carries a human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 81 kDa. The protein migrates as 100-110 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
No activity loss was observed after storage at: In lyophilized state for 1 year (4 °C), After reconstitution under sterile conditions for 3 months (-70 °C).
Delta-like protein 4 (DLL4) is also known as Drosophila Delta homolog 4 (Delta4). DLL4 contains one DSL domain and eight EGF-like domains. DLL4 is expressed in vascular endothelium. DLL4 involved in angiogenesis, negatively regulates endothelial cell proliferation and migration and angiogenic sprouting. DLL4 plays a role in the Notch signaling pathway. DLL4 activates Notch-1 and Notch-4.
