    摘要: A method for the preparation of a novel recombinant DNA, which comprises (1) cleaving with an endonuclease a temperate phage DNA having an endonuclease-sensitive region not in the DNA segment participating in the replication of phage DNA and the integration of phage DNA into a host chromosome but at least in the DNA segment carrying genetic information for the coat protein production and another DNA carrying intended genetic information, (2) adding DNA-ligase to the mixture of both cleft DNA's, and (3) recovering from the mixture a phage DNA having its coat protein producing ability deleted by the replacement of the DNA segments carrying genetic information for the coat protein production with a DNA fragment carrying the intended information.

    摘要: A bacteriophage which is characterized by the presence of one or more restriction enzyme sites downstream from the late promoter up to the cohesive end, and none or a permissible number of restriction enzyme sites upstream from the late promoter to the cohesive end is useful as an expression vector. The vector can be used to obtain high expression of DNA inserted at the restriction enzyme site downstream from the late promoter up to the cohesive end.

The ion exchange resin is maintained in a porous container in a suspended state in the electrocoating bath, and is used in a quantity of not more than the chemical equivalent of excess counter-ion to be removed from the bath. Bath control is easily achieved without any coagulation trouble as often observed in conventional column methods.
