Patent number: 6509151Abstract: The present invention relates to a DNA molecule conferring on Mycobacterium tuberculosis an ability to enter mammalian cells and to survive within macrophages. The protein encoded by this gene fragment is useful in vaccines to prevent infection by Mycobacterium tuberculosis, while the antibodies raised against this protein can be employed in passively immunizing those already infected by the organism. Both these proteins and antibodies may be utilized in diagnostic assays to detect Mycobacterium tuberculosis in tissue or bodily fluids. The protein of the present invention can be associated with various other therapeutic materials, for administration to mammals, particularly humans, to achieve uptake of those materials by such cells.Type: GrantFiled: February 22, 1995Date of Patent: January 21, 2003Assignee: Cornell Research Foundation, Inc.Inventor: Lee W.

Patent number: 6015556Abstract: A compound comprises a target cell-specific portion, such as an antibody specific to tumor cell antigens, and an inactivating portion, such as an enzyme, capable of converting a substance which in its native state is able to inhibit the effect of a cytotoxic agent into a substance which has less effect against said cytotoxic agent. The prolonged action of a cytotoxic agent at tumor sites is therefore possible while protecting normal tissues from the effects of the cytotoxic agent.Type: GrantFiled: June 30, 1997Date of Patent: January 18, 2000Assignee: Enzacta R & D LimitedInventor: Kenneth Dawson Bagshawe

Patent number: 5942421Abstract: A single celled organism, vector, and method are provided for continuous production of excreted proteins in the absence of substantial host cell replication and without the necessity for the addition of antibiotics to control cell replication. The vector has (1) an inducible promoter capable of activating a gene for a protein to be produced under conditions that substantially inhibit host cell replication, and (2) a hybrid gene containing a signal sequence fused to a gene for the protein to be produced. Large quantities of the transformed single celled organisms containing the vector can be grown in the absence of inducing conditions, thereby reducing the problem of plasmid loss. Further, the protein is produced under conditions that substantially inhibit host cell replication, thereby allowing immobilization of the single celled organism by entrapment or attachment within or onto a solid support surface. The single celled organism can be immobilized after, before or simultaneously with induction.Type: GrantFiled: November 18, 1997Date of Patent: August 24, 1999Assignee: Cornell Research Foundation, Inc.Inventors: Michael L. Shuler, David B. Wilson
