Abstract: Described herein are isolated bi-specific antigen binding constructs, e.g., antibodies. The bi-specific antigen binding constructs include two antigen binding polypeptide constructs, e.g., a Fab and an scFv. The first antigen-binding polypeptide construct monovalently and specifically binds to extracellular domain 4 (ECD4) of HER2 (human epidermal growth factor receptor 2); the second antigen-binding polypeptide construct monovalently and specifically binds to an extracellular domain (ECD) of HER3 (human epidermal growth factor receptor 3). One antigen binding polypeptide construct is a Fab format and the other antigen binding polypeptide construct is an scFv format. The bi-specific antigen binding constructs includes an Fc having two Fc polypeptides each having a CH3 domain for dimerization. Each Fc polypeptide is linked to the C-terminus of one of the antigen binding polypeptide constructs with or without a linker.

Abstract: The present application is directed to heterodimeric antibodies and methods of use.

Abstract: We provide an antibody capable of binding to an intracellular PRL-I or PRL-3 polypeptide, in which the antibody is capable of binding to an epitope bound by antibody 269, antibody 223 or antibody 318. Such anti-PRL antibodies may be capable of binding to intracellular PRL-I or PRL-3. They may be suitable for use as therapies against cancer or metastasis thereof, or in clinical diagnosis to identify PRL-3 or PRL-1 positive patients.

Abstract: Microvesicles play essential roles in disease progression. The present invention provides a microvesicle membrane protein and application thereof. Disclosed is a method comprising phosphorylated CSE1L (cellular apoptosis susceptibility protein)- or CSE1L-binding agents for microvesicle isolation, analysis, or binding for disease diagnosis.

Abstract: This invention is in the area of improved anti-aP2 antibodies and antigen binding agents, and compositions thereof, which target the lipid chaperone aP2/FABP4 (referred to as “aP2”) for use in treating disorders such as diabetes, obesity, cardiovascular disease, fatty liver disease, and/or cancer, among others. In one aspect, improved treatments for aP2 mediated disorders are disclosed in which serum aP2 is targeted and the biological activity of aP2 is neutralized or modulated using low-binding affinity aP2 monoclonal antibodies, providing lower fasting blood glucose levels, improved systemic glucose metabolism, increased systemic insulin sensitivity, reduced fat mass, reduced liver steatosis, reduced cardiovascular disease and/or a reduced risk of developing cardiovascular disease.

Abstract: The present invention is directed to bi-specific diabodies that comprise two or more polypeptide chains and which possess at least one Epitope-Binding Site that is immunospecific for an epitope of PD-1 and at least one Epitope-Binding Site that is immunospecific for an epitope of LAG-3 (i.e., a “PD-I×LAG-3 bi-specific diabody”). More preferably, the present invention is directed to bi-specific diabodies that comprise four polypeptide chains and which possess two Epitope-Binding Sites that are immunospecific for one (or two) epitope(s) of PD-1 and two Epitope-Binding Site that are immunospecific for one (or two) epitope(s) of LAG-3 (i.e., a “PD-1×LAG-3 bi-specific, tetra-valent diabody”).

Abstract: The present invention relates to engineered heteromultimeric proteins, and more specifically, to methods for producing and purifying heterodimeric proteins, such as bispecific antibodies and other heterodimeric proteins comprising immunoglobulin-like hinge sequences. Methods for producing and purifying such engineered heterodimeric proteins and their use in diagnostics and therapeutics are also provided.
