To improve the growth of mouse hybridoma 2c3.1 secreting anti-Hepatitis B surface antigen monoclonal antibody (anti-HBsAg MAb), we had constructed an enriched medium and observed the effects of fetal bovine serum and serum-free supplements including human serum albumin, 'insulin and transferrin', and monoethanolamine. For further enhancement of growth, the concentrations of two major energy sources, glucose and glutamine, were strengthened with various ratios in the enriched medium. Maximum cell growth and monoclonal antibody production obtained in various ratios of glucose/glutamine with an inoculation concentration of 2x105 cells/ml were 0.73x106-4.62x106 cells/ml and 65.1-422.6 ug/ml, respectively. Glutamine was round to be a major energy source and a limiting nutrient in comparison to glucose for 2c3.1 cell cultivation in enriched media with low serum.
