7782 results about "Monoclonal" patented technology

Monoclonal cells are a group of cells produced from a single ancestral cell by repeated cellular replication. Thus they can be said to form a single clone. The term monoclonal comes from the Ancient Greek monos, meaning "alone" or "single", and klon, meaning "twig".

Antibody formulations

The present application describes antibody formulations, including monoclonal antibodies formulated in histidine-acetate buffer, as well as a formulation comprising an antibody that binds to domain II of HER2 (for example, Pertuzumab), and a formulation comprising an antibody that binds to DR5 (for example, Apomab).

Delivery of enzymes to the brain

Delivery of large enzymes to the brain via transport across the blood-brain barrier (BBB) utilizing conjugates, or fusion proteins, which are composed of a therapeutic enzyme and a BBB targeting agent (molecular Trojan horse). The enzyme is missing in the brain, and does not cross the BBB. The molecular Trojan horse is a receptor-specific endogenous peptide, or peptidomimetic monoclonal antibody (MAb), that undergoes receptor-mediated transport across the BBB, thereby carrying into brain the attached enzyme.

Prevention and treatment of HCV infection employing antibodies that inhibit the interaction of HCV virions with their receptor

Human monoclonal antibodies binding to epitopes common to type 1 and 2 HCV are provided, as well as conformationally conserved HCV E2 2a and 2b proteins. Compositions comprising the antibodies find use in diagnosis and therapy. The antibodies recognize conformational epitopes that are conserved across multiple genotypes of HCV. Thus the antibodies have the potential to be useful in the prevention and treatment of the majority of HCV infections. A subset of the antibodies (CBH-2, CBH-5, CBH-7, CBH-8C, CBH-8E, and CBH-11) have the ability to prevent the binding of HCV E2 proteins of multiple genotypes to human CD81, a possible co-receptor for HCV infection. A subset of the antibodies (CBH-2 and CBH-5) have been shown to inhibit the binding of HCV virions (as opposed to purified E2 protein) to human CD81. A further subset of the antibodies (CBH-4D, CBH4B, CBH-8C, and CBH-9) have been shown to prevent HCV envelope mediated fusion using an HCV psuedotype system.

Reshaped human antibody to human interleukin-6

A reshaped antibody comprising: (A) L chains comprising: (1) a human C region, and (2) an L chain V region comprising human L chain FRs and L chain CDRs of a mouse monoclonal antibody; and (B) H chains comprising: (1) a human H chain C region, and (2) an H chain V region comprising human H chain FRs, and H chain CDRs of a mouse monoclonal antibody to human IL-6. Since the major portions of the reshaped human antibody are derived from human, and the mouse CDRs are less immunogenic, then the present reshaped human antibody is less immunogenic, and therefore inhibits information transfer by IL-6, and is promising as a therapeutic agent for diseases caused by IL-6.
