RECOMBINANT VASCULAR ENDOTHELIAL GROWTH FACTOR (VEGF) SECRETING Escherichia coli BL21 (pVEGF-A165) CELL STRAIN Russian patent published in 2010 - IPC C12N1/21 C12N15/12 C07K14/475 C12R1/19 

Abstract RU 2395568 C2

FIELD: chemistry; biochemistry.

SUBSTANCE: invention pertains to biotechnology. In particular, the invention relates to an Escherichia coli BL21 (pVEGF-A165) strain and can be used to produce a vascular endothelial growth factor - GST-VEGF-A165 protein. A novel Escherichia coli BL21 (pVEGF-A165) cell strain is obtained, which is transformed by the pGEX-VEGF-A165 plasmid. This strain produces a recombinant GST-VEGF-A165 protein.

EFFECT: invention enables to obtain a Escherichia coli BL21 (pVEGF-A165) strain which is stably transformed by plasmid which codes VEGF, and which secrete this factor in extracellular space when cultured in vitro.
