摘要: The present invention provides a vector plasmid capable of efficient tumor necrosis factor (TNF) production, a process capable of efficient TNF production in a host transformed with said plasmid and a composition containing the TNF produced by said process.The novel plasmid of the present invention is characterized by having inserted therein a DNA fragment that has a phage-derived promoter region upstream of a structural gene for TNF and in which a DNA fragment containing an E. coli gene-derived transcription termination coding base sequence (terminator) is joined immediately downstream of a base sequence coding for the termination of translation of said structural gene.

摘要: The L and H chains of the human anti-HBs antibody can be produced by the genetic recombination techniques to provide the desired human anti-HBs antibody easily on a large scale. The invention relates to nucleotide base sequences coding for the respective polypeptides that constitute the L and H chains of the anti-HBs antibody, expression plasmids containing them, and transformants prepared by transformation with the expression plasmids.
