Abstract: Compositions and methods are provided for producing materials having increased immunoglobulin binding capacities, the materials including full-length or truncated forms of protein A, protein G, protein A/G, protein L and other immunoglobulin-binding proteins or peptides, which moieties contain polypeptide domains, or polypeptide-oligopeptide combinations. Also provided are separation matrices containing the moieties and methods of using the separation matrices for separation of immunoglobulins or immunoglobulin containing proteins.

Abstract: Tumor Necrosis Factor-? (TNF?) promotes an inflammatory response resulting in many clinical problems associated with autoimmune disorders such as rheumatoid arthritis, ankylosing spondylitis, inflammatory bowel disease, psoriasis, hidradenitis suppurativa, and refractory asthma. Dysregulation of TNF production is implicated in a variety of human diseases including Alzheimer's disease, cancer, major depression, and inflammatory bowel disease. These disorders are treated with a TNF? inhibitor.

Abstract: Methods and pharmaceutical compositions for preventing and/or treating acute and chronic inflammation and autoimmune diseases are provided herein. Tumor necrosis factor-? (TNF?) promotes an inflammatory response, which causes clinical problems associated with inflammation and autoimmune disorders such as rheumatoid arthritis, ankylosing spondylitis, inflammatory bowel disease, psoriasis, hidradenitis suppurativa, and refractory asthma. TNF? is also implicated in promoting pathogenesis of diabetic retinopathy leading to loss of retinal microvascular cells. Methods herein contain the step of administering a prophylactic and/or therapeutic formulation of a pharmaceutical composition containing a recombinant soluble human TNF receptor or portions thereof which are TNF? inhibitors.
