  • Antibiotics-independent vector for constant high-expression and method for gene expression using the same
    Patent number: 7049097
    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.

  • Antibiotics-independent vector for constant high-expression and method for gene expression using the same
    Publication number: 20030084474
    Abstract: The present invention relates to an antibiotic-independent vector for constant high-expression and a method for gene expression using this vector. The stable expression of a recombinant gene is maintained by a stable plasmid through the use of genes essential for the growth and proliferation of the microorganism as a marker, instead of antibiotics, such as ampicillin.
