WebbDefinition. Recombinant protein expression in bacteria requires the insertion of a DNA fragment ( open reading frame, ORF) into an expression vector, routinely a plasmid vector and the transferral of this vector into bacterial cells ( transformation ). The cells are then cultured and induced to express the desired protein.
