Abstract
A murine hybridoma cell line (167.4G5.3) was cultured in batch mode using IMDM containing different serum concentrations and bovine serum albumin (BSA). Cell growth and death, metabolism and antibody production were studied in these cultures. The cells were more susceptible to shear in the stationary and in the decline phase of growth as evidenced by higher death rates. Cell growth was best at high serum concentrations with high specific growth and low specific death rates. When BSA was used instead of serum in IMDM, no protective effect was observed. Cell metabolism and monoclonal antibody production rates were not influenced by the level of serum or by BSA. The use of serum in commercial serum-free media (OPTI-MEM) also resulted in no change in both growth and death rates.
