Tepoditamab
Based on 1 Customer Validation
Tepoditamab (MCLA-117) is a full-length human IgG1 bispecific monoclonal antibody that binds to CLEC12A of myeloid cells and CD3 of cytotoxic T cells. Among others, CLEC12A is a myeloid differentiation antigen. Tepoditamab kills AML leukaemia mother cells and AML leukaemia stem cells, induces T cell-mediated proliferative lysis of AML cells. Tepoditamab induces upto 30-fold T-cell expansion. Tepoditamab results in moderate to strong cytokine (IFNγ, IL-6, IL-8, IL-10, and TNFα) and IFNγ release in human whole blood and PBMC, respectively. Tepoditamab can be used in acute myeloid leukaemia (AML) research.

Human IgG1 kappa
Human
CLEC12A & CD3E
Tepoditamab binds specifically to CLEC12APOS and CD3POS cells within the normal haematopoietic compartment[2].
Tepoditamab (1,000 ng/mL, 24-48 h) induces upregulation of CD69 and CD25 on CD4 and CD8 T cells after 24 and 48 h in HL60 cells concentration-dependently[2].
Tepoditamab (0.1 ng/mL-10 μg/mL, 48 h) induces a concentration-dependent T cell-mediated lysis of HL60 cells at 100 ng/mL and above, as well as a mean EC50 of 68 ng/mL[2].

Loaded Tepoditamab on AHC2 biosensor, can bind CLEC12A/MICL Protein, Human (Biotinylated, HEK293, His-Avi, HY-P77633) with an affinity constant of 1.185E-08 M as determined in BLI assay. -
Immobilized CD3 epsilon Protein, Human (HEK293, His, HY-P70506) can bind Tepoditamab. The EC50 for this effect is 74.47 ng/mL. -
Immobilized CLEC12A/MICL Protein, Human (HEK293, Fc, HY-P77631) can bind Tepoditamab. The EC50 for this effect is 67.71 ng/mL. -
Flow cytometric analysis of 1×106 Jurkat cells labelling CD3E (red) with Tepoditamab (HY-P99390). 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.
