专利汇可以提供Production of heterogenic protein by escherichia coli专利检索,专利查询,专利分析的服务。并且PURPOSE: To simply improve productivity of heterogenic protein by transforming a specific plasmid to give a transformant of Escherichia coli, infecting the transformant with a phage infected bacterium and culturing.
CONSTITUTION: DNA fragment to code genetic information of desired heterogenic protein in a manifestable form is bonded to the downstream of transcription initiation signal and translation initiation signal derived from T4 phage, one of virulent phage and inserted into a plasmid replicable with Escherichia coli to give a hybridoma plasmid (A). Then the component A is inserted into Escherichia coli JM105 strain, etc., to give a transformant (B), the transformant B is multiplied in a desired medium and infected with T4 phage denB and/or alc variant in low multiplicity of infection to give a phage infected bacterium (C). Then the bacterium C is subjected to aerated culture at 20-40°C for 0.5-10 hours, the prepared cell is extracted, purified by gel filtration method to produce heterogenic protein.
