Abstract: The invention provides a method for purifying viral vectors containing therapeutic genes for use in gene therapy. The invention comprises a method of purification from a cell lysate of a recombinant viral vector containing a therapeutic gene, which comprises: a) treating said lysate with an enzymatic agent that selectively degrades both unencapsulated DNA and RNA; b) chromatographing the treated lysate from step a) on a first resin; and c) chromatographing the eluant from step b) on a second resin; wherein one resin is an anion exchange resin and the other is an immobilized metal ion chromatography (IMAC) resin.

Abstract: A method and pharmaceutical composition for the treatment of cancer using a gene delivery system, such as a viral vector delivery system, comprising a therapeutic gene wherein the gene delivery system is formulated in a buffer comprising a delivery-enhancing agent such as ethanol.

Abstract: This invention provides a family of monoclonal antibodies specific for epitopes of p110.sup.RB protein present in the nucleus. These antibodies have superior properties that prove useful for the detection of p110.sup.RB or its complexes with other cellular regulatory proteins in cells and in cell lysates. This invention also provides hybridoma cell lines that produce such monoclonal antibodies and methods of using these antibodies diagnostically, prognostically and therapeutically. Further, the invention provides a method for isolating proteins associated with p110.sup.RB proteins.
