METHOD FOR PRODUCING RECOMBINANT PROTEIN

摘要

Provided is a method for producing tocilizumab, the method including: the culture of animal cells that secrete tocilizumab in a medium containing soybean hydrolysate, which improves the degree of galactosylation of the sugar chains of a recombinant protein; and the isolation of tocilizumab from the culture broth obtained by culturing the animal cells.
