Plamotamab
Based on 1 Customer Validation
Plamotamab (XmAb-13676) is a human bispecific antibody (bsAb) that binds CD3 and CD20. Plamotamab recruits cytotoxic T cells to kill CD20+ expressing tumor cells. Plamotamab induces a mild hematologic reaction (MR), and results in tumor regression in vivo.

Flow cytometric analysis of 1×106 Jurkat cells labelling CD3E (red) with Plamotamab (HY-P99776). 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.
