  • Publication number: 20230085485
    Abstract: In one embodiment, a masked monoclonal antibody (mAb) is provided, the mAb, encoded by a nucleic acid sequence or an amino acid sequence molecule comprising a signal sequence, a masking epitope sequence, a linker sequence that is cleavable by a protease specific to a target tissue; and an antibody or a functional fragment thereof. In another embodiment, a masked monoclonal antibody (mAb) is provided, which includes a therapeutic mAb and a mask, the mask comprising protein A and protein L attached by a protease cleavable linker.
