A human hybrid cell line named F2N78 was developed by somatic fusion of human embryonic kidney cells (HEK293) and Burkitt’s lymphoma cells (Namalwa). F2N78 cell line inherited advantageous phenotypes such as ease to suspension, high transfection efficacy, EBV genome insertion in chromosome, and human-specific glycosylation. For that reason, this cell line can be used for the production of human therapeutic antibody or vaccines. In order to be used in commercial processes, the formulation of the culture medium for F2N78 cell line has been investigated to optimize culture conditions. Glucose and glutamine are the most commonly employed carbon and nitrogen sources and directly affect cell growth. However, their rapid depletion was found to cause the accumulation of lactate and ammonia during F2N78 cell culture. To support cell growth with the generation of minimal quantities of lactate and ammonia, amino acids were chosen as the alternatives for glucose and glutamine. In previous studies, amino acids produced during cell culture were excluded from the culture medium. We calculated the percentage of amino acid consumption during cell culture and the results are as follows: Arg (50%), Asn (28%), Asp (100%), Cys (32%), His (29%), Ile (61%), Leu (70%), Lys (33%), Met (61%), Ser (89%), and Val (59%). These amino acids are selected for the design of MS004 medium by fortified amino acid study (FAS). In this study, effects of the addition of amino acids on cell growth of F2N78 cell line are going to be presented.
