Omburtamab
Based on 1 Customer Validation
Omburtamab (Mab 8H9) is a mouse monoclonal immunoglobulin G1 (IgG1) antibody targeting B7-H3. Omburtamab specifically binds to the glycoprotein antigen B7-H3, which is widely expressed on the surface of tumor cells. As a targeting carrier for recombinant toxins, it delivers PE38 to inhibit cellular protein synthesis and induce cytotoxicity in antigen-expressing cancer cells. Omburtamab can be used in research related to glioma, breast cancer, osteosarcoma and neuroblastoma.

Immobilized CD276/B7-H3 Protein, Human (433a.a, HEK293, His, HY-P70652) can bind Omburtamab. The EC50 for this effect is 45.43 ng/mL. -
Flow cytometric analysis of 1.5×106 THP-1 cells with Omburtamab (HY-P99157, red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa 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 kappa Isotype Control (HY-P99001, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
