  • Publication number: 20210393776
    Abstract: The present disclosure relates generally to multi-specific Fab fusion proteins (MSFP) which comprise an antibody Fab fragment with both N-termini fused to a fusion moiety (fusion moiety A or B). MSFP containing the Fab fragment exhibit significantly reduced binding ability of the Fab fragment to the Fab target. Binding of the Fab to its target is restored when the MSFP is clustered on a cell surface by binding of the fusion moieties to their target. The reduced binding of the Fab to its target, especially when presented on a cell surface in its native state, absent fusion moiety binding provides advantages such as: reduced side effects and allows desirable pharmacological effects of selectivity and specificity in a controlled manner.

    Abstract: The present disclosure provides an anti-fuse, which includes at least one anti-fuse unit. The anti-fuse unit includes: a field-effect transistor, including a substrate, and a first doping region, a second doping region and a gate electrode that are disposed on the substrate; and a first electrode, arranged on the substrate and forming an anti-fuse capacitor with the substrate, the first electrode being connected to the first doping region, and configured to break down the anti-fuse capacitor by voltage adjustment between the second doping region and the substrate and write data to the anti-fuse unit, or configured to detect a current flowing through the second doping region by voltage adjustment for the gate electrode and determine whether to write data to the anti-fuse unit. By using the first electrode and the substrate as a pair of plates of the anti-fuse capacitor, a port of the anti-fuse unit may be omitted.
