METHOD OF PRODUCING PEPTIDES, RECOMBINANT PLASMID FOR USE IN THE SAME AND ANIMAL CELLS TRANSFORMED WITH THE SAME

摘要

D0-1-45362C/KT/87 A method of producing desired peptides by transforming mammalian cells and cultivating the transformed cells can be improved by using myeloma cells as the mammalian cells and/or using a vector having the SV40 early promoter sequence on both the 5' upstream and 3' downstream sides of the gene coding for the desired peptide.
