Smart Cell Targeting

Stealth-Body

Proprietary Fc mutations that switch off effector function while leaving antigen binding intact.

Across the Fc gamma receptor panel, it shows no binding and no effector activity above background.

Effector engagement is one way an antibody acts on tissue it was never aimed at. Closing that route matters most when the antibody is carrying a payload.
