Patent number: 8414894Abstract: 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.Type: GrantFiled: December 30, 2011Date of Patent: April 9, 2013Assignee: Abbott Biotechnology Ltd.Inventors: Jochen G.

Patent number: 8362217Abstract: 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.Type: GrantFiled: December 20, 2007Date of Patent: January 29, 2013Assignee: EMD Millipore CorporationInventors: Wilson Moya, Jad Jaber

Patent number: 8231868Abstract: 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.Type: GrantFiled: May 4, 2010Date of Patent: July 31, 2012Assignee: Yale UniversityInventors: Richard Leslie Edelson, Carole Berger, Michael Girardi
