Method of producing peptides recombinant pasmid for use in the same and animal cells transformed with the same

摘要

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.
