Building from of the well-understood cellular targeting abilities of antibodies, we combine the intrinsic efficiency of enzymes with the unique specificity of metal-free click chemistry to replace the native antibody glycan with a stably attached therapeutic payload.
Any antibody can be converted into a stably conjugated ADC in just a few days by modifying the native antibody glycan using our highly efficient enzymes and metal-free click chemistry approach.
Multiple independent experiments confirm that the native glycan position is likely one of the best for attaching ADC payloads to antibodies.
