The present invention relates to specific binding members, particularly antibodies and fragments thereof, which bind to amplified epidermal growth factor receptor (EGFR) and to the de2-7 EGFR truncation of the EGFR. In particular, the epitope recognized by the specific binding members, particularly antibodies and fragments thereof, is enhanced or evident upon aberrant post-translational modification. These specific binding members are useful in the diagnosis and treatment of cancer. The binding members of the present invention may also be used in therapy in combination with chemotherapeutics or anti-cancer agents and/or with other antibodies or fragments thereof.

The present invention relates to antibodies specifically binding PD-1, TIM-3 or PD-1 and TIM-3, polynucleotides encoding the antibodies or fragments, and methods of making and using the foregoing.

Provision of an affinity carrier using a mutant VHH antibody. An affinity carrier comprising: a solid phase carrier; and an immunoglobulin-binding protein bound to the solid phase carrier; wherein the immunoglobulin-binding protein comprises a mutant VHH antibody or a fragment of the mutant VHH antibody that recognizes an epitope in at least one region selected from the group consisting of amino acids 127 to 184 of SEQ ID NO: 22 and amino acids 13 to 210 of SEQ ID NO: 23.

Isolated antigen binding molecules that specifically bind to an anti-CD19 scFv comprising SEQ ID NO: 1 are provided. The antigen binding molecules can be used in the methods provided herein.

Isolated human monoclonal antibodies which bind to and inhibit human CD25, and related antibody-based compositions and molecules, are disclosed. The human antibodies can be produced by a hybridoma, a transfectoma or in a nonhuman transgenic animal, e.g., a transgenic mouse, capable of producing multiple isotypes of human monoclonal antibodies by undergoing V-D-J recombination and isotype switching. Also disclosed are pharmaceutical compositions comprising the human antibodies, nonhuman transgenic animals, hybridomas and transfectomas which produce the human antibodies, and therapeutic and diagnostic methods for using the human antibodies.

An Fc variant containing a 2,6-sialylated glycosylation modification is provided. The Fc variant has an increased affinity for human FcRn and an increased 2,6-sialylation level. The Fc variant can reduce the level of IgG in the blood, and 2,6-sialic acid thereof has an anti-inflammatory effect. A protein, composition or kit including the Fc variant is also provided.

The invention relates to methods of determining whether or not an individual has or is likely to develop a neurological disease and related methods and kits.

The present invention relates to antibodies specifically binding PD-1, TIM-3 or PD-1 and TIM-3, polynucleotides encoding the antibodies or fragments, and methods of making and using the foregoing.

The present invention provides antibodies and antigen-binding fragments thereof that bind to the antibody pembrolizumab (pembrolizumab). These antibodies are useful, for example, for use as positive controls in assays for detecting the presence of anti-drug antibodies in a sample, e.g., the blood of a patient who has been administered pembrolizumab.

Isolated human monoclonal antibodies which bind to and inhibit human CD25, and related antibody-based compositions and molecules, are disclosed. The human antibodies can be produced by a hybridoma, a transfectoma or in a nonhuman transgenic animal, e.g., a transgenic mouse, capable of producing multiple isotypes of human monoclonal antibodies by undergoing V-D-J recombination and isotype switching. Also disclosed are pharmaceutical compositions comprising the human antibodies, nonhuman transgenic animals, hybridomas and transfectomas which produce the human antibodies, and therapeutic and diagnostic methods for using the human antibodies.
