  • Publication number: 20240076389
    Abstract: AXL-specific antibodies and uses therefor are described, including monoclonal and single domain antibodies. Such antibodies bind to cell surface expressed human AXL at an epitope in an immunoglobulin-like (IgL) domain of the AXL ectodomain. The antibody may be used in an antibody-drug conjugate (ADC), for example in the treatment, detection or staging of cancer. The antibody may be biparatopic.

  • Patent number: 10259864
    Abstract: Campylobacter jejuni is a leading cause of bacterial food-borne diseases in humans, ranging from acute diarrheal disease to neurological disorders. An isolated or purified antibody or fragment thereof specific to C. jejuni is described. The antibody or fragment thereof binds to a flagellar protein and reduces motility of C. jejuni. The antibody or fragment thereof is derived from a heavy chain IgG variable domain fragment (VHH) of a camelid animal immunized with C. jejuni flagellar protein. A multivalent form, as well as a phage format, of the antibody or fragment thereof is described. Methods of reducing presence of C. jejuni in an animal or an animal environment, methods and formulations for treating C. jejuni infection, and method of detecting C. jejuni are also described.
