  • Patent number: 8414894
    Abstract: Human antibodies, preferably recombinant human antibodies, that specifically bind to human tumor necrosis factor ? (hTNF?) are disclosed. These antibodies have high affinity for hTNF? (e.g., Kd=10?8 M or less), a slow off rate for hTNF? dissociation (e.g., Koff=10?3 sec?1 or less) and neutralize hTNF? activity in vitro and in vivo. An antibody of the invention can be a full-length antibody or an antigen-binding portion thereof. The antibodies, or antibody portions, of the invention are useful for detecting hTNF? and for inhibiting hTNF? activity, e.g., in a human subject suffering from a disorder in which hTNF? activity is detrimental. Nucleic acids, vectors and host cells for expressing the recombinant human antibodies of the invention, and methods of synthesizing the recombinant human antibodies, are also encompassed by the invention.

  • Patent number: 8362217
    Abstract: The present invention relates to a selectively soluble polymer capable of binding to a desired biomolecules in a mixture containing various biological materials and the methods of using such a polymer to purify a biomolecule from such a mixture. The polymer is soluble in the mixture under a certain set of process conditions such as pH or temperature and/or salt concentration and is rendered insoluble and precipitates out of solution upon a change in the process conditions. The polymer is capable of binding to the desired biomolecule (protein, polypeptide, etc) and remains capable of binding to that biomolecule even after the polymer is precipitated out of solution. The precipitate can then be filtered out from the remainder of the stream and the desired biomolecule is recovered such as by elution and further processed.

  • Patent number: 8293213
    Abstract: A method and system for affecting a thrombus after ischemic stroke. The method may include injecting a plurality of magnetic particles into a bloodstream and moving or distorting a thrombus formed or lodged in the bloodstream using a magnetic force to manipulate the magnetic particles. The method may include conjugating ferromagnetic particles, paramagnetic particles, or superparamagnetic particles to a thrombus-specific attachment agent such as an anti-fibrin antibody, and injecting the conjugated particles into the bloodstream. Thereafter, the thrombus may be agitated, broken apart, or dissolved using a magnetic field to exert a magnetic force on the conjugated particles. The method may also include injecting a thrombolytic agent into the bloodstream to interact with and further dissolve the thrombus.

  • Patent number: 8231868
    Abstract: Methods are provided for suppressing the immune system response in recipients of transplanted organs, tissues or cells. An extracorporeal quantity of blood from the intended transplant recipient is treated to induce monocytes contained in the blood to differentiate and form dendritic cells. The maturation of the dendritic cells is truncated at a stage where the dendritic cells can inactivate T cell clones which would otherwise generate an undesired immune system response. The immature dendritic cells can be directly administered to the transplant recipient, or the dendritic cells can be co-incubated with the bone marrow or stem cell preparation, prior to transplantation, in order to suppress or eliminate anti-recipient donor T cells contaminating the bone marrow or stem cell preparation. The methods can be used to suppress graft versus host disease in recipients of transplanted bone marrow or stem cells, or to suppress rejection of transplanted organs or tissue.

  • Patent number: 8217153
    Abstract: Various system and method embodiments of the present invention are directed to separating target molecules from complex solutions by affinity column chromatography using organic-solvent-containing eluants. In one embodiment of the present invention, an eluant containing an organic-solvent is used, at a first pH, to remove non-target solutes and suspended entities from an affinity chromatography column. The pH of the eluant is then changed to a second pH, and the organic-solvent-containing eluant is used to elute target molecules from the affinity column chromatography.
