Biological Activity
Human IgG2 kappa
Human
DLL4
Demcizumab (0-100 μg/mL) binds to human DLL4 but not murine DLL4, and blocks DLL4 binding to Notch1 receptor in a FACS-binding assay[3].
Demcizumab (20 μg/mL, 48 h) reduces HES1 and DTX1 mRNA expression in PDTALL cells[4].
Demcizumab (0-80 μg/mL, 1 or 2 or 3 days) promotes cell death and early apoptosis in PDTALL13 cells[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:PDTALL13 (patient-derived T-ALL 13) cell
-
Concentration:0, 0.5, 1, 5, 10, 20, 40, 80 μg/mL
-
Incubation Time:1 or 2 or 3 days
-
Result:Dose-dependently inhibited cell viability.
Demcizumab is efficacious alone or in combination with Irinotecan (7.5 mg/kg) in OMP-C8 colon tumors[3].
Demcizumab (20 mg/kg/week, i.p.) increases mice survival in irradiated NRG mice injected PDTALL13 cells[4].

Flow cytometric analysis of 1X106 HUVEC cells with Demcizumab (HY-P99261, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa Fluor 488-conjugated AffiniPure Goat Anti-Human IgG H&L (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG2 kappa (HY-P99002, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
