  • Patent number: 11332538
    Abstract: Methods and compositions involving polypeptides having an aglycosylated antibody Fc domain are provided. In certain embodiments, polypeptides have an aglycosylated Fc domain that contains one or more substitutions compared to a native Fc domain. Additionally, some embodiments involve an Fc domain that is binds some Fc receptors but not others. For example, polypeptides are provided with an aglycosylated Fc domain that selectively binds C1q, and optionally activating Fc receptors, but that is significantly reduced for binding to the inhibitory Fc?RIIb receptor. Furthermore, methods and compositions are provided for promoting complement dependent cytotoxicity (CDC) using a polypeptide having a modified aglycosylated Fc domain and a second non-Fc binding domain, which can be an antigen binding region of an antibody or a non-antigen binding region. Some embodiments concern antibodies with such polypeptides, which may have the same or a different non-Fc binding domain.

  • Patent number: 10651571
    Abstract: A metal leaf spring protection structure of electrical connection terminal includes a main body having a base section defined with a first end and a second end. The first end is connected with a first section and a locating section. The second end is connected with a bight section and a second section. The locating section has a head section and a tail section. The tail section extends to a position of the bight section to form a hook-like structure for providing an elastic action force and a support system. The locating section is positioned in the reciprocally moving path of the second section to set up a moving end point of the second section to improve the shortcomings of the conventional metal leaf spring that when plugging in the conductive wire, the metal leaf spring is over-bent to affect the pressing and securing effect.
