Constitutive versus thermoinducible expression of heterologous proteins in Escherichia coli based on strong PR,PL promoters from phage lambda
14 May 2003
Abstract excerpt
Constitutive and thermoinducible expression plasmids based on strong P(R),P(L) promoters from phage lambda were compared for production of TNF-alpha and its analogs under various conditions. Much higher accumulation of TNF was obtained in a constitutive system, so the wider applicability of such systems was studied. In constitutive systems, proteolytically susceptible proteins can be produced easily at low...
