    摘要: A method for expressing recombinant molecules in bacterial hosts in a defined medium in the absence of antibiotic selection is disclosed. The method uses an expression vector comprising a regulatable promoter by which the production of foreign proteins may be controlled during the growth phase of the culture, and origin of replication maintaining medium vector copy number and a transcriptional promoter.

    摘要: This invention relates to a process for obtaining antibodies in soluble and correctly folded and assembled form. It comprises a step to raise the temperature at a time in the process selected to facilitate the subsequent isolation of soluble, correctly folded and assembled antibody, substantially free of other antibody-related material. The operating temperature may be raised at any stage in the microbial fermentation or eukaryotic cell culture, or at any stage during extraction and purification of the antibodies.
