Abstract: The present invention relates to anti-S1P agents, for example, humanized monoclonal antibodies, and their uses for detection of S1P or for treatment of diseases and conditions associated with S1P.

Abstract: The present invention relates to altered antibody Fc regions and uses thereof.

Abstract: The present invention relates to compositions that comprise an anti-S1P monoclonal antibody, antibody fragment, or derivative in a carrier, particularly a buffered, hypertonic aqueous solution, as well as to kits containing such compositions, and methods for using such compositions for treatment of diseases and conditions associated with S1P.

Abstract: The invention provides heterochimeric antibodies and/or fragments thereof comprising (i) hypervariable region sequences wholly or substantially corresponding to sequences found in antibodies from a donor species; (ii) constant region sequences wholly or substantially corresponding to sequences found in antibodies from a target species which is different from the donor species; and (iii) heavy and/or light chain variable framework sequences which contain at least three non-CDR residues corresponding to sequences found in antibodies from a target species and at least three contiguous non-CDR residues corresponding to sequences found in antibodies from a donor species. The invention further provides antibody to canine or feline or equine antigens, e.g., CD20 or CD52, and methods of making and using antibodies as described.

Abstract: Compositions and methods for making and using anti-LPA agents, for example, monoclonal antibodies, are described. Variable domain and complementarity determining region amino acid sequences of several monoclonal antibodies against LPA are disclosed, as is a consensus anti-LPA monoclonal antibody variable domain sequence.

Abstract: The present invention provides a composition which links genotype and phenotype and provides a method for in vitro protein evolution and screening using said composition. The invention also facilitates the identification and isolation of proteins with selected properties from large pools of proteins. The composition and method of the invention can be used with eukaryotic (both mammalian and plant) and prokaryotic translation systems.

Abstract: The invention provides antibodies with superior therapeutic efficacy and related methods of engineering such antibodies to increase their stability and resistance to proteases, e.g., in the digestive tract. Protease cleavage motifs are identified and subsequently modified to reduce or eliminate cleavage at that site. Methods of employing these orally deliverable antibodies as therapeutic compositions, particularly against gastrointestinal pathogens are also provided herein. In one aspect, the invention provides combinations of monoclonal antibodies, e.g., “synthetic polyclonals,” that work synergistically to neutralize bacterial toxins, particularly enteric bacterial toxins such as Clostridium difficile toxin A.

Abstract: Compositions and methods for producing monoclonal antibodies and their derivatives reactive against bioactive lipid targets are described. These compositions include derivatized lipids, each of which comprises a bioactive lipid that having a polar head group and at least one hydrocarbon chain (e.g., a lysolipid such as lysophosphatidic acid or sphingosine-1-phosphate) in which a carbon atom has been derivatized with a pendant reactive group; immunogens made by linking a derivatized lipid to a carrier moiety (e.g., a carrier protein, polyethylene glycol, colloidal gold, alginate, or a silicone bead); monoclonal antibodies and derivatives produced by immunizing an animal with such an immunogen; and therapeutic and diagnostic compositions containing such antibodies and antibody derivatives.
