METHOD OF OBTAINING OF GENI-ENGENIERING ECDERONIC FACTOR OF PERSON GROWTH, PLASM RECOMBINATION DNA pER-hEGF, CODING HYBRID PROTEIN CAPABLE FOR AUTO-CATALYTIC SPLITTING, CAPABLE FOR AUTO-CATALYTIC SPLITTING WITH GENERATING OF EPIDERMAL FACTOR OF PERSON GROWTH, AND STAMP Escherichia coli ER2566/pER-hEGF-PRODUCER OF MENTIONED PROTEIN Russian patent published in 2008 - IPC C12N15/00 

Abstract RU 2323976 C2

FIELD: production methods.

SUBSTANCE: cells Escherichia coli, transform the plasm DNA pER-hEGF with producing of recombination stamp Escherichia coli ER2566/pER-hEGF - producer of hybrid protein Int-hEGF, includes with the structure of recombinated epidermal factor of personal growth the structure of inteine. It is provided the cultivation of achieved stamp Escherichia coli ER2566/pER-hEGF with following cell distraction in buffer substance by ultrasound, after the cell distraction hybrid protein is separated as the body of inclusions, they are dissolved in buffer, contains 6 M carbamide, renatured the hybrid protein, adsorbed on the chitinous sorbent, and then is it raised auto-catalyc splitting with рН changing from 10.0 to 7.0 with generating the solid product, which is eluted from sorbent.

EFFECT: invention allowes to obtain high productive recombinated stamp of bacterial stamp-producer of hybrid protein.
