    • A method for preparing and isolating a transformation vector containing CSF/cDNA is described. The method comprises:preparing RNA from a cell that produces CSF;preparing polyadenylated messenger RNA from said RNA;preparing single stranded cDNA from said messenger RNA;converting the single stranded cDNA to double stranded cDNA;inserting the double stranded cDNA into transformation vectors and transforming bacteria with said vector to form colonies;picking pools of 200 to 500 colonies each and isolating plasmid DNA from each pool;transfecting the plasmid DNA into suitable host cells for expressing CSF protein;culturing the transfected cells and assaying the supernatant for CSF activity; andselecting CSF positive pools and screening the colonies used to make the pool to identify a colony having CSF activity. Also described are a cDNA coding for a protein having CSF activity (i.e. CSF/cDNA), a microorganism or cell line transformed with a recombinant vector containing such CSF/cDNA, and a method for producing CSF protein by expressing said CSF/cDNA by culturing a microorganism or cell line. The invention also provides a method of purifying the CSF proteins and the purified proteins so produced.

    • A method for identifying and isolating clones containing DNA coding for a desired protein is described. DNA prepared from a cell that expresses the desired protein is inserted into an isolation expression vector having means for replication (as a means of producing DNA) and a suitable promoter for expression of said DNA in a predetermined mammalian host cell as well as means for replication in a bacterial cell. The transient expression vector is then inserted into a bacterial cell for replication of the DNA. Pools of DNA, prepared from a predetermined number of bacterial clones so that the nucleic acids (DNA and RNA) is substantially free of other bacterial contaminants are transfected or microinjected into mammalian host cells and conditioned medium from growing such cells is tested for the presence of the desired protein. Positive pools are selected and the clones used to make the pool are screened to identify and isolate the clone containing the desired DNA.
