• Transfection host for some immune checkpoint concerning the NFAT signaling pathway
• The discovery of T cell activators by the NFAT signaling bioactivity
• Screen for anti-human CD3xTAA BsAb.


Expression analysis of human CD3 on NFAT (Luc) Jurkat Reporter Cell by FACS.
NFAT (Luc) Jurkat Reporter Cell were stained with APC-R700 labeled Anti-Human CD3 antibody or APC-R700 labeled Isotype antibody.

Activating of NFAT signaling bioactivity by anti-human CD3 antibody (RLU).
This reporter cell was incubated with serial dilutions of anti-human CD3 antibody (Cat. No. CDE-M120a). The EC50 of anti-human CD3 antibody was approximately 0.078 μg/mL.

Activating of NFAT signaling bioactivity by anti-human CD3 antibody (FOLD).
This reporter cell was incubated with serial dilutions of anti-human CD3 antibody (Cat. No. CDE-M120a). The max induction fold was approximately 137.

Bioactivity detection of Anti-human CD3xCD19 bispecific antibody.
This reporter cell was incubated with serial dilutions of Blinatumomab (CD3×CD19 BsAb) in the presence of Raji cells that express human CD19 endogenously. The EC50 of Blinatumomab incubated with Raji cells is approximately 0.66 pM with the max induction fold 842.

Passage stability analysis by anti-human CD3 antibody stimulation.
The continuously growing NFAT (Luc) Jurkat Reporter Cell was stimulated with serial dilutions of anti-human CD3 antibody (Cat. No. CDE-M120a). Anti-human CD3 antibody stimulated response demonstrates passage stabilization (fold induction and EC50) across passage 15-34.
