Growth kinetics of hybridoma cells: (2) The effects of varying energy source concentrations.
Commercial media used for the growth of hybridoma cells contain different glucose concentrations. We have attempted to establish the optimal levels of glucose required for maximum hybridoma cell yields by studying the energy source metabolism of two murine hybridoma cell lines in several commercial media in static 25 cm2 flask cultures. The glucose and lactate quotients and growth yields from glucose of the two cell lines were similar in all media. Glucose limited growth in DME containing lg/L. Glucose supplementation to 2g/L in DME significantly increased cell and antibody yields. When fructose was used as a substitute for glucose the fructose quotient of one cell line was found to be similar to its glucose quotient whereas that of the other cell line was significantly reduced compared to its glucose quotient.
