  • Patent number: 8652468
    Abstract: Described are conjugates formed by an antibody fragment covalently attached to a nonproteinaceous polymer, wherein the apparent size of the conjugate is at least about 500 kD. The conjugates exhibit substantially improved half-life, mean residence time, and/or clearance rate in circulation as compared to the underivatized parental antibody fragment. Also described are conjugates directed against human vascular endothelial growth factor (VEGF), human p185 receptor-like tyrosine kinase (HER2), human CD20, human CD18, human CD11a, human IgE, human apoptosis receptor-2 (Apo-2), human tumor necrosis factor-? (TNF-?), human tissue factor (TF), human ?4?7 integrin, human GPIIb-IIIa integrin, human epidermal growth factor receptor (EGFR), human CD3, and human interleukin-2 receptor ?-chain (TAC) for diagnostic and therapeutic applications.

  • Patent number: 8012754
    Abstract: A process for purifying an antibody is provided. In this process, a mixture containing the antibody and a contaminant is subjected to low pH hydrophobic interaction chromatography (LPHIC) at low salt concentration. The antibody is eluted from the column in the fraction which does not bind thereto. This process can be preceded and followed by other purification steps.

  • Patent number: 7423128
    Abstract: The present invention is related to antibodies directed to the antigen properdin and uses of such antibodies. In particular, in accordance with the present invention, there are provided fully human monoclonal antibodies directed to the antigen properdin. Nucleotide sequences encoding, and polypeptides comprising, heavy and light chain immunoglobulin molecules, particularly sequences corresponding to contiguous heavy and light chain sequences spanning the framework regions and/or complementarity determining regions (CDR's), specifically from FR1 through FR4 or CDR1 through CDR3, are provided. Hybridomas or other cell lines expressing such immunoglobulin molecules and monoclonal antibodies are also provided.
