RECOMBINANT PLASMID DNA pTrcTREN-IL-13 ENCODING POLYPEPTIDE WITH PROPERTIES OF HUMAN INTERLEUKIN-13, AND STRAIN OF BACTERIA Escherichia coli BL21(DE3)/pTrcTREN-IL13 - PRODUCENT OF POLYPEPTIDE WITH PROPERTIES OF HUMAN INTERLEUKIN-13 |
摘要 |
FIELD: chemistry, genetics. ^ SUBSTANCE: invention relates to the field of genetic engineering and can be used for obtaining human interleukin-13 (IL-13). On the basis of plasmid pTrcTEGF and optimised for bacterial expression cDNA encoding a mature form of human interleukin-13 a recombinant plasmid DNA pTrcTREN-IL13 is constructed. This plasmid DNA provides biosynthesis of polypeptide with properties of human interleukin-13 in cells of E.coli. As a result of transformation of strain of bacteria Escherichia coli BL21(DE3) by the said plasmid, strain of E.coli BL21(DE3)/pTrcTREN-IL13/pTrcTREN-IL13 is obtained, which produces polypeptide with properties of human interleukin-13. ^ EFFECT: ensuring an increase in the level of heterological expression of polypeptide with properties of human interleukin-13 at reduced quantity of inductor. ^ 2 cl, 4 dwg, 1 tbl, 4 ex |
