Patent number: 5871997Abstract: Methods and compositions are provided for facilitating gene therapy procedures involving the transduction of target cells with retroviral vector particles in the presence of complement containing body fluids. The reduction of levels of galactose alpha (1,3) galactosyl epitopes on the retroviral vector particles and/or the blockade of antibody binding to such epitopes have been found to render the particles less sensitive to inactivation by complement mediated mechanisms, and to thus allow transduction in the presence of complement containing body fluids. Means are provided for obtaining such reductions.Type: GrantFiled: March 6, 1995Date of Patent: February 16, 1999Assignee: Alexion Pharmaceuticals, Inc.Inventors: Russell P. Rother, Scott A.

The other orientation, i.e., the orientation in which the second amino acid sequence is amino terminal to the first amino acid sequence, only produces C3 inhibitory activity. Nucleic acid molecules encoding such proteins are also provided.Type: GrantFiled: March 3, 1994Date of Patent: May 6, 1997Assignee: Alexion Pharmaceuticals, Inc.Inventors: William L.
