Human IgG1(D356E/L358M) kappa
Human
IGF1R/CD221
Robatumumab (0.02-80 nM; 0.5 or 4 h) downregulates IGF-IR and inhibits both basal and IGF-I-induced phosphorylation of IGF-IR and IRS-1 in SK-N-FI cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:SK-N-FI cells
-
Concentration:0.02-80 nM
-
Incubation Time:0.5 or 4 hours
-
Result:Inhibited the IGF-I–stimulated phosphorylation of IGF-IR after treatment 0.5 h.
Resulted in both inhibition of IGF-IR phosphorylation and receptor downregulation after treatment 4 h.
Resulted in a dose-dependent inhibition of the IGF-I–stimulated IRS-1 phosphorylation.
Robatumumab (intravenous injection; 0.02-0.5 mg/mouse; twice weekly; 35 d) inhibits the osteosarcoma growth in xenograft model[2].
Robatumumab (intravenous injection; 0.1 or 0.5 mg/mouse; twice weekly; 14 d) inhibits the SJCRH30 and RD rhabdomyosarcoma cell growth in xenograft model[2].
Robatumumab (intravenous injection; 0.1 or 0.5 mg/mouse; twice weekly; 2 w) blocks effectively pediatric tumor cell proliferation in vivo[2].
Robatumumab (intravenous injection; 0.5 mg/mouse; once; day 11 post-inoculation) modulates the blood vessel formation via its antiangiogenesis effect[2].

Flow cytometric analysis of 1X106 MCF-7 cells with Robatumumab (HY-P99218, 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 (AF488) (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1(E356D/M358L) kappa (HY-P990100, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
