β¦ Synopsis
A human-human hybridoma HB4CS secreting human IgM class monoclonal antibody was examined for possible adaptation to a protein-free medium.
HB4C5 could be cultured for more than two months in a protein-free medium without any significant changes in antibody production.

Five mouse-human hybridoma cell lines secreting human IgM class monoclonal antibodies were examined for possible adaptation to a protein free medium. Four were successfully adapted to the medium. The adapted cell lines could be cultured for more than two months without any changes in their cell grow
The expressions of transferrin receptor and ferritin in a human-human hybridoma in protein-free media were examined. The regulation of the expressions of the two proteins appeared to be decoupled in protein-free cultures. Such cultures also exhibited much higher ferritin expression and endogenous ir
