Virtual burrow assay for a diversity of neurological and psychiatric disorders

The invention relates to a method for determining if a test compound, or a mix of compounds, modulates the interaction between two proteins of interest. The determination is made possible via the use of two recombinant molecules, one of which contains the first protein a cleavage site for a proteolytic molecules, and an activator of a gene. The second recombinant molecule includes the second protein and the proteolytic molecule. If the test compound binds to the first protein, a reaction is initiated whereby the activator is cleaved, and activates a reporter gene.

DNA encoding the T cell surface protein CD4 and use of fragments of CD4 in the treatment of AIDS

The invention relates to processes for inserting into eucaryotic cells a multiplicity of DNA molecules which includes genes coding for desired proteinaceous materials. The insertion of multiple copies of desired genes is accomplished by cotransformation with the desired genes and with amplifiable genes for a dominant selectable marker in the presence of successively higher amounts of an inhibitor. Alternatively, the insertion of multiple copies of desired genes is accomplished by transformation using DNA molecules formed by ligating a DNA molecule including the desired gene to a DNA molecule which includes an amplifiable gene coding for a dominant selectable phenotype such as a gene associated with resistance to a drug in the presence of successively higher amounts of an agent such as a drug against which the gene confers resistance so that only those eucaryotic cells into which multiple copies of the amplifiable gene have been inserted survive. Eucaryotic cells into which multiple copies of the amplifiable gene have been inserted additionally include multiple copies of the desired gene and may be used to produce multiple copies of proteinaceous molecules. In this way otherwise rare proteinaceous materials may be obtained in higher concentrations than are obtainable using conventional techniques.

The present invention relates to processes for inserting DNA into eucaryotic cells, particularly DNA which includes a gene or genes coding for desired proteinaceous materials for which no selective criteria exist. The insertion of such DNA molecules is accomplished by cotransforming eucaryotic cells with such DNA together with a second DNA which corresponds to a gene coding for a selectable marker. This invention also concerns processes for producing proteinaceous materials such as insulin, interferon protein, growth hormone and the like which involve cotransforming eucaryotic cells with DNA which codes for these proteinaceous materials, growing the cotransformed cells for production of the proteinaceous material and recovering the proteinaceous material so produced. The invention further relates to processes for inserting into eucaryotic cells a multiplicity of DNA molecules which includes genes coding for desired proteinaceous materials. The insertion of multiple copies of desired genes is accomplished by cotransformation with the desired genes and with amplifiable genes for a dominant selectable marker in the presence of successively higher amounts of an inhibitor.

In this way otherwise rare proteinaceous materials may be obtained in higher concentrations than are obtainable using conventional techniques.

Processes for inserting DNA into eucaryotic cells and for producing

Multiple copies of a foreign DNA I coding for the production of a protein may be introduced into eucaryotic cells by cotransforming suitable cells with foreign DNA I and with foreign DNA II which includes a functionally deficient, amplifiable gene coding for a selectable or identifiable trait, preferably carried on the same DNA molecule as a foreign DNA III, which includes a functional, amplifiable gene coding for another selectable or identifiable trait. The cotransformation is carried out under suitable conditions permitting selection or identification of cells expressing the gene on DNA I or that on DNA III, but not that on DNA II. The cotransformed cells so identified or selected are recovered and cloned under conditions where the functionally deficient gene on DNA II is expressed. Cells expressing the gene on DNA II are recovered. They contain multiple copies of DNA I. This method can be used to produce mRNA transcripts or protein products such as human and animal growth hormone, insulin and the like.
