Vepsitamab
Based on 1 Customer Validation
Vepsitamab (AMG 199) is a bispecific T-cell engager (HLE BiTE) that binds to MUC17 and CD3. Vepsitamab directs CD3-positive cells to target MUC17-positive cells. Vepsitamab induces cell activation and proliferation. Vepsitamab is applicable to research related to gastric cancer and gastroesophageal junction (g/gej) cancer.

Immobilized Vepsitamab can bind Human MUC17 Protein (His Tag). The EC50 for this effect is 2.10 ng/mL. -
Immobilized Vepsitamab can bind Human CD3 epsilon/CD3e Protein (ECD, His Tag). The EC50 for this effect is 2.35 ng/mL. -
Flow cytometric analysis of 1×106 Jurkat cells labelling CD3E (red) with Vepsitamab (HY-P99523). 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.
