Patent number: 7611866Abstract: The invention overcomes the deficiencies of the prior art by providing a rapid approach for isolating polypeptides capable of anchoring heterologous polypeptides to a bacterial inner membrane. In the technique, libraries of candidate anchor polypeptides are expressed as fusions with a heterologous polypeptide that is capable of being detected when bound to the inner membrane. In bacteria expressing a functional anchor sequence, the heterologous polypeptide becomes bound to outer face of the inner membrane. Bacteria with the functional anchor sequence can be identified by removing the outer membrane to remove non-anchored heterologous polypeptide followed by detection of anchored heterologous polypeptide. Such bacteria may be detected in numerous ways, including use of direct fluorescence or secondary antibodies that are fluorescently labeled, allowing use of efficient techniques such as fluorescence activated cell sorting (FACS).Type: GrantFiled: March 18, 2005Date of Patent: November 3, 2009Assignee: Board of Regents, The University of Texas SystemInventors: George Georgiou, Ki Jun Jeong, Barrett R.

Of these N-glycosylated sites more than 70% are glycosylated with an oligomannose having a structure defined by Man(8 to 10)-GlcNAc(2). Furthermore, the ratio of the oligomannose with structure Man(7)-GlcNAc(2) over the oligomannose with structure Man(8)-GlcNAc(2) is less than or equal to 0.45. Less than 10% of the oligomannoses is terminated with an ?1,3 linked mannose. The HCV envelope proteins of the invention are particularly suited for diagnostic, prophylactic and therapeutic purposes. A suitable eukaryotic cell for production of the HCV envelope proteins of the invention is a Hansenula cell.Type: GrantFiled: April 24, 2002Date of Patent: July 3, 2007Assignee: Innogenetics N.V.Inventors: Fons Bosman, Erik Depla, Geert Deschamps, Erwin Sablon, Manfred Suckow, Isabelle Samson, Gert Verheyden

Patent number: 7202356Abstract: The regulatory sequences (i.e., promoter regions, introns and enhancers) associated with the Yarrowia lipolytica gene encoding fructose bis-phospate aldolase (FBA1) have been found to be particularly effective for the expression of heterologus genes in oleaginous yeast. The promoter regions of the invention have been shown to drive high-level expression of genes involved in the production of ?-3 and ?-6 fatty acids.Type: GrantFiled: November 12, 2004Date of Patent: April 10, 2007Assignee: E. I. du Pont de Nemours and CompanyInventors: Dana M. Walters Pollak, Quinn Qun Zhu

Patent number: 7198919Abstract: The isolation of the yeast ?-factor genes is described. The promoter and signal peptide portions are isolated and joined to DNA coding for proteins heterologous to yeast in a plasmid which is used to transform yeast cells. The yeast expresses the heterologous DNA and processes and secretes the heterologous protein.Type: GrantFiled: May 24, 1995Date of Patent: April 3, 2007Assignee: Genentech, Inc.Inventor: Arjun Singh

Patent number: 6962796Abstract: The invention provides recombinant plasmids containing in DNA sequences coding for human preproparathyroid hormone. The invention further provides microorganisms, for example E. coli, transformed by these plasmids. The invention also provides a plasmid for insertion into yeast and a transformed yeast in which the plasmid contains DNA coding for parathyroid hormone. Parathyroid hormone is then secreted by the transformed yeast. Further the invention provides alternate polypeptides having parathyroid hormone activity, including PTH analogs, fragments and extensions, and provides alternate leader sequences and secretion signal sequences which can be used in the present invention. Finally, there are provided methods for purification of the secreted PTH hormone and/or derivatives.Type: GrantFiled: September 25, 2000Date of Patent: November 8, 2005Assignee: NPS Allelix Corp.Inventors: Kaare M. Gautvik, Peter Alestrom, Tordis Beate Oyen, Odd Stokke Gabrielsen

Patent number: 6924125Abstract: This invention demonstrates the utility of a yeast expression system for the expression of functional heterologous multi-domain proteins in yeast. The yeast expression system allows for the inclusion of a plurality of (up to three) modular expression cassettes which may encode multiple polypeptide chains of a heterologous multi-domain protein on a single plasmid (Twin Cassette). Because multiple polypeptide chains may be encoded for by the expression cassettes of the present invention in a single vector, the system can produce equivalent amounts of the multiple polypeptide chains, thereby enhancing the yield of a functional heterologous multi-domain protein. For example, functional monoclonal antibodies (MAbs) comprising a heavy chain and a light chain of an immunoglobulin (IgG), and functional immunotoxins comprising an antibody domain and an oxidase toxin may be produced using the Yeast expression system of the present invention.Type: GrantFiled: October 19, 2001Date of Patent: August 2, 2005Assignee: Apolife, Inc.Inventors: Nalini Motwani, Robert Blackburn

Patent number: 6858384Abstract: Peripheral blood leucocytes incubated with a semi-synthetic phage antibody library and fluorochrome-labeled CD3 and CD20 antibodies were used to isolate human single chain Fv antibodies specific for subsets of blood leucocytes by flow cytometry. Isolated phage antibodies showed exclusive binding to the subpopulation used for selection or displayed additional binding to a restricted population of other cells in the mixture. At least two phage antibodies appeared to display hithereto unknown staining patterns of B lineage cells. This approach provides a subtractive procedure to rapidly obtain human antibodies against known and novel surface antigens in their native configuration, expressed on phenotypically defined subpopulations of cells. Importantly, this approach does not depend on immunization procedures or the necessity to repeatedly construct phage antibody libraries.Type: GrantFiled: May 24, 2001Date of Patent: February 22, 2005Assignee: Crucell Holland B.V.Inventors: Leon W M M Terstappen, Ton Logtenberg
