    Abstract: This invention relates to the transient expression of heterologous polypeptides in mammalian cell lines. Specifically it relates to an expression-enhanced cell line derived from a parent cell line, the expression-enhanced cell line comprising nucleic acid encoding Epstein-Barr Virus Nuclear Antigen 1 or a functional derivative, analogue, or variant thereof; and further comprising: (a) a nucleic acid encoding an exogenous glutamine synthetase; (b) a nucleic acid encoding an endogenous glutamine synthetase, wherein the endogenous glutamine is arranged to have enhanced enzymatic activity and/or enhanced expression relative to the parent cell line under comparable conditions; or (c) both (a) and (b).
