Abstract: The invention is a cell culture medium that can include reduced or no serum and that enhances the performance of serum-free media for cell culture. The medium supports the growth of cells for both small scale and large scale propagation of cells. The invention also includes a method of cultivating cells using the cell culture medium of the present invention.

Abstract: A method for producing tissue plasminogen activator (t-PA) in eukaryotic host cells is disclosed. Enhanced levels of t-PA production are obtained by co-amplification of the t-PA gene through treatment of cultures transformed with mutant or wild type DHFR with methotrexate.

Abstract: A method for controlled production of a desired mature protein in a vertebrate host cell through the use of a polycistronic expression vector, which contains sequences coding for the desired protein and a secondary protein, is described. Both coding sequences are governed by the same promoter and are separated by translational stop and start signal codons. The expression of the secondary sequence effects control over the expression of the sequence coding for the desired protein, and the secondary protein functions as a marker for selection of transfected cells.
