Theoretical Molecular Weight |
57.6 kDa |
Apparent Molecular Weight |
Due to glycosylation, the protein migrates to 60-70 kDa based on Bis-Tris PAGE result. |
Formulation |
Lyophilized from 0.22μm filtered solution in 50mM Tris, 150mM NaCl (pH 7.5). |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Storage & Stability |
Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |
Target Background |
DLL1, a Notch signaling ligand, is significantly overexpressed in ERα luminal breast cancer. Intriguingly, DLL1 overexpression correlates with poor prognosis in ERα luminal breast cancer, but not in other subtypes of breast cancer. In addition, this effect is specific to DLL1, as other Notch ligands (DLL3, JAGGED1, and JAGGED2) do not influence the clinical outcome of ERα patients. DLL1-mediated Notch signaling in breast cancer is important for tumor cell proliferation, angiogenesis, and cancer stem cell function. |
