Abstract
An antibiotic-independent vector for stable vector maintenance and high protein expression and a method for gene expression using this vector are disclosed. The stable maintenance of the vector is due to expression of a glutamic acid racemase to complement a D-glutamic acid auxotroph. No antibiotics, such as ampicillin, are necessary for the stable maintenance of this vector.
