Abstract
Different cell culture media were compared for their ability to support and promote the growth of stable hybridoma cell lines derived from three commonly used parental murine myelomas. Supplemented Dulbecco's modified Eagle's media (DMEM) and RPMI 1640 media were studied. The DMEM-based media were found to support greater numbers of cells for longer time periods than were the RPMI 1640-based media. Aminopterin supplemented medium was shown to be significantly less effective in supporting hybridoma reproduction and viability than medium without aminopterin. Antibody levels were directly related to cell concentration and viability regardless of the medium used for the hybridoma culture. An optimally formulated DMEM-based medium is suggested as the medium of choice for hybridoma propagation and maintenance.
