Delta-like protein 4, Drosophila Delta homolog 4, Delta4, delta like canonical Notch ligand 4, AOS6, hdelta2.
Delta-Like4 or DLL4 is implicated in the Notch signaling transduction as Notch ligand. DLL4 down regulates endothelial cell proliferation, migration and angiogenic sprouting. DLL4 is crucial for retinal progenitor proliferation &furthermore required for suppressing rod fates in late retinal progenitors & for proper generation of other retinal cell types. Also, at some stages in the spinal cord neurogenesis, DLL4 inhibits V2a interneuron fate.
DLL4 Human Recombinant produced in HEK293 is a single glycosylated polypeptide chain containing 504 amino acids (27-529 a.a) and having a molecular mass of 55.1kDa. DLL4 is fused to a 6 amino acid His-tag at C-terminus & purified by proprietary chromatographic techniques.
DLL4 protein solution (0.25mg/ml) containing Phosphate Buffered Saline (pH 7.4) and 10% glycerol.
Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 95.0% as determined by SDS-PAGE.
