Vectors and methods for high throughput co-expressions
View Patent ↗The present invention includes vectors and methods for high throughput co-expression.
1. A method for the expression of a polypeptide, the method comprising expressing said polypeptide by an expression vector,
the expression vector comprising a first nucleotide sequence operably encoding zeomycin resistance and a second nucleotide sequence operably encoding a ccdB polypeptide, wherein the first nucleotide sequence and the second nucleotide sequence are flanked within the same attR1 and attR2 sites, and wherein the polynucleotide comprises a G144704 cassette having SEQ ID NO:4,
or the expression vector comprising a first nucleotide sequence operably encoding tetracycline resistance and a second nucleotide sequence operably encoding a ccdB polypeptide, wherein the first nucleotide sequence and the second nucleotide sequence are flanked within the same attR3 and attR4 sites, and wherein the polynucleotide comprises a tet Multisite having SEQ ID NO: 7.
2. The method of claim 1 , improving the solubility of said polypeptide.
3. The method of claim 1 , wherein the expression vector is selected from the group consisting of pDEST-C1 (SEQ ID NO:1), pDEST-C2 (SEQ ID NO:2), pDEST-C3 (SEQ ID NO:3), pDEST-CM1 (SEQ ID NO:5), pDEST-CM2 (SEQ ID NO:6), pDEST-CM3 (SEQ ID NO:8), pDEST-CM4 (SEQ ID NO:9), pDEST-CS (SEQ ID NO:17), pDEST-CS1 (SEQ ID NO:18), pDEST-CS2 (SEQ ID NO:19), pDEST-CS3 (SEQ ID NO:20), pDEST-CS4 (SEQ ID NO:21), pDEST-CMZ1 (SEQ ID NO:22), and pDEST-CMZc1 (SEQ ID NO:23).
4. The method of claim 1 , wherein the expression vector comprises a first nucleotide sequence operably encoding zeomycin resistance and a second nucleotide sequence operably encoding a ccdB polypeptide, wherein the first nucleotide sequence and the second nucleotide sequence are flanked within the same attR1 and attR2 sites, and wherein the polynucleotide comprises a G144704 cassette having SEQ ID NO:4.
5. The method of claim 4 , wherein the expression vector is selected from the group consisting of pDEST-C1 (SEQ ID NO:1), pDEST-C2 (SEQ ID NO:2), pDEST-C3 (SEQ ID NO:3), pDEST-CS (SEQ ID NO:17), pDEST-CS1 (SEQ ID NO:18), pDEST-CS2 (SEQ ID NO:19), pDEST-CS3 (SEQ NO:20), pDEST-CS4 (SEQ ID NO:21), pDEST-CMZ1 (SEQ ID NO:22), and pDEST-CMZcl (SEQ ID NO:23).
6. The method of claim 1 , wherein the expression vector comprises a first nucleotide sequence operably encoding tetracycline resistance and a second nucleotide sequence operably encoding a ccdB polypeptide, wherein the first nucleotide sequence and the second nucleotide sequence are flanked within the same attR3 and attR4 sites, and wherein the polynucleotide comprises a tet Multisite having SEQ ID NO: 7.
7. The method of claim 6 , wherein the expression vector is selected from the group consisting of is selected from the group consisting of pDEST-CM1 (SEQ ID NO:5), pDEST-CM2 (SEQ ID NO:6), pDEST-CM3 (SEQ ID NO:8), pDEST-CM4 (SEQ ID NO:9), pDEST-CMZ1 (SEQ ID NO:22), and pDEST-CMZc1 (SEQ ID NO:23).
