- 摘要:
- 为研究BHK-21细胞的生长及代谢动力学特征,试验采用低密度静置培养方法,每天测定细胞生长密度和活力,并利用多参数生化分析仪测定培养液中Gluc、Lac、Gln和NH4+的含量,计算细胞指数生长期的比代谢速率。结果表明:BHK-21细胞生长曲线呈S型,最大增殖密度为50.3×104 upf?mL-1,倍增时间为21.1 h;对数生长期Gluc和Gln的比消耗速率为-3.79 mg?(106cells)-1?d-1和-9.95 μmol?(106cells)-1?d-1,Lac和NH4+的比生成速率为2.81 mg?(106 cells)-1?d-1和6.30 μmol?(106cells)-1?d-1。
- Abstract:
- In order to research the growth and metabolism kinetic characteristics of BHK-21 cells,low cell density cultured method was used to determine cell density and vitality every day.The contents of Gluc,Lac,Gln,and NH4+ in medium were determined by multiparameter biochemical analyzer,and the specific metabolic rate were calculated.The results showed that the growth curve of BHK21 cells was “S” type,the largest density was 50.3×104 upf?mL-1and the doubling time was 21.1 h.Specific consumption rate of Gluc and Gln were -3.79 mg〖DK1〗?(106cells)-1?d-1and -9.95 μmol?(106cells)-1?d-1 in logarithmic phase,and specific generation rate of Lac and NH4+ were 2.81 mg〖DK1〗?(106 cells)-1?d-1和6.30 μmol?(106cells)-1?d-1.
