    摘要： The present invention provides stabilized immunoglobulin molecules that have increased storage stability and/or in vivo half-lives due to the mutation of one or more amino acids that would otherwise render the immunoglobulin molecules susceptible to degradation. In a preferred embodiment, the stabilized immunoglobulins of the invention have mutations at the heavy chain constant domain hinge region. Such stabilized immunoglobulin molecules, i.e., immunoglobulin molecules with increased storage stability have one or more of the following advantages they are more readily transported and/storable for longer periods and/or less stringent conditions than non-stabilized counterparts; that smaller amounts and or less frequent dosing is required in the therapeutic, prophylactic or diagnostic use of such stabilized molecules.

    摘要： The present invention relates to novel molecules (Fc variants) comprising at least one antigen binding region and an Fc region that further comprises a modified hinge which improves stability and/or alters the binding of Fc to one or more metal ion and/or one or more Fc ligand (e.g., FcγRs) and/or modulates effector function. More specifically, this invention provides Fc variants that are less susceptible to metal ion-mediated cleavage and/or have modified binding affinity to one or more FcγR and/or C1q. Additionally, the Fc variants have altered antibody-dependent cell-mediated cytotoxicity (ADCC) and/or complement dependent cytotoxicity (CDC) activity. Furthermore, the modified hinge of the Fc variants retains a similar flexibility to the wild type hinge. The invention further provides methods and protocols for the application of said Fc variants particularly for therapeutic purposes.
