Patent number: 7816130Abstract: Provided are novel vectors and viral vectors capable of expressing exogenous gene or exogenous nucleic acid sequences in a target cell of interest, such as T cells, bone marrow cells, epithelial cells, liver cells and the like. The nucleic acid components of the vectors may include one or more native promoter/enhancer regions having modified sequence segments, one or more non-native promoter/enhancer or non-native promoter's gene or gene segment, and a native viral vector terminator or processing signal or segment thereof. The viral vectors comprise a virus or viral portion having on the surfaces or envelopes adsorption components, one for a packaging cell line and the other for delivery to a target cell. Other viral vectors provided by this invention have two components on their surfaces or envelopes, one of which is native to the virus and the other being non-native and capable of adsorbing to the target cell while being incapable of adsorbing to a native cell for the viral vector.Type: GrantFiled: June 4, 2003Date of Patent: October 19, 2010Assignee: Enzo Therapeutics, Inc.Inventors: Dakai Liu, Elazar Rabbani

Patent number: 6221581Abstract: Double hybrid or multihybrid probes and compositions are usefully combined with capture assay and immobilization to provide for detection processes in which target polynucleotides can be detected or the presence or absence of genetic mutations or defects in genetic material can be determined. The capture assay involves capturing a hybrid structure, e.g., single hybrid, double hybrid or multihybrid, or capturing a complex formed by reacting a hybrid structure with a complex forming moiety, e.g., protein, such as a binding protein including an antibody. Immobilization can also be employed prior to hybridization or complexation in which instance a polynucleotide probe can be fixed to a matrix or solid support, e.g., natural or synthetic. Capture and immobilization can be carried out using direct and indirect binding and attachment techniques. Targets can be detected directly or indirectly by using a signal generating moiety and labels.Type: GrantFiled: June 7, 1995Date of Patent: April 24, 2001Assignees: Enzo Diagnostics, Inc., c/o Enzo Biochem, Inc.Inventors: Dean L.

Patent number: 5989809Abstract: The present invention provides a method for detecting the presence of a target polynucleotide in a sample. The method comprises the steps of (a) contacting the sample under hybridizing conditions with (i) a single-stranded polynucleotide probe capable of hybridizing to the target polynucleotide and comprising a polynucleotide and at least one intercalating molecule attached to a nucleotide of the polynucleotide by means of a linker arm, and (ii) a background-reducing reagent which chemically modifies the intercalating molecule when the probe to which it is attached is single-stranded; and (b) detecting a property change resulting from the intercalation of the intercalating molecule into a target-probe hybrid, thereby detecting the target polynucleotide. The intercalating molecule which is part of the polynucleotide probe induces a change in a property, in either the probe, the target polynucleotide or a target-probe hybrid.Type: GrantFiled: January 24, 1995Date of Patent: November 23, 1999Assignee: Enzo Diagnostics, Inc.Inventor: Jannis G.
