Establishment of stable mouse myeloma cells constitutively secreting human tissue-type plasminogen activator.
Expression plasmids for human tissue-type plasminogen activator (t-pA) were introduced into mouse myeloma cells and stable cell lines constitutively secreting t-pA established by selection with mycophenolic acid. Expression of t-pA is driven either by the simian virus 40 early promoter or by immunoglobulin regulatory elements of either light or heavy chains of the mouse. The availability of myeloma cells secreting a heterologous protein is of importance for biotechnological applications, because large-scale fermentation of myeloma cells is well established.
