  • Patent number: 9835626
    Abstract: Disclosed are surprising new methods and compositions for isolating extracellular microvesicles such as exosomes, particularly disease-related and phosphatidylserine (PS)-positive extracellular microvesicles as exemplified by tumor- and viral-derived exosomes. The methods of the invention are rapid, efficient, cost-effective and, importantly, are suitable for use with large volumes of biological fluids and produce antigenically intact extracellular microvesicles and exosomes. The methods and compositions are based on the surprising use of acetate buffers to isolate large quantities of extracellular microvesicles, particularly tumor-derived exosomes, from solution, without damaging their morphological or functional properties or antigenicity.

  • Patent number: 9421256
    Abstract: Disclosed are human antibodies that specifically inhibit VEGF binding to only one (VEGFR2) of the two primary VEGF receptors. The antibodies effectively inhibit angiogenesis and induce tumor regression, and yet have improved safety due to their specificity. The present invention thus provides new human antibody-based compositions, methods and combined protocols for treating cancer and other angiogenic diseases. Advantageous immunoconjugate compositions and methods using the new VEGF-specific human antibodies are also provided.

  • Patent number: 8956616
    Abstract: Disclosed are new phosphatidylserine binding constructs with surprising combinations of properties, and a range of diagnostic and therapeutic conjugates thereof. The new constructs effectively bind phosphatidylserine targets in disease and enhance their destruction, and can also specifically deliver attached imaging or therapeutic agents to the disease site. Also disclosed are methods of using the new construct compositions, therapeutic conjugates and combinations thereof in tumor vasculature targeting, cancer diagnosis and treatment, and for treating viral infections and other diseases.
