  1. Methods : cell culture in serum - free medium, indirect immunofluorescence cytochemistry were used

    方法：採用無血清細胞培養技術，間接免疫細胞化學染色法。
  2. Abstract : adopting the serum - free and animal - source - free medium domestication express cell efficiently, setting up to express system efficiently, suspending culture cell, can raise the cell density in the scale turn the production, strengthen the cell vitality, control cell to propagate level, extension cell culture period, increase the target protein of yield, raise product quality, simplification of produces technics, reduce production cost, then raising the efficiency that the scale turns culture

    提要：採用無血清無動物組分培養基馴化高效表達細胞，構建高效表達系統，懸浮培養細胞，可以在規模化生產中，提高細胞密度，增強細胞活力，控制細胞增殖水平，延長細胞培養周期，增加目標蛋白的產量，提高產品質量，簡化生產工藝，降低生產成本，進而提高規模化培養的效能。
  3. A successful cell strain for biopharmaceutical production must conform to the following characteristics : the cells could produce high level of recombinant proteins ; the cell should be adapted to serum - free or protein - free medium ; the cells should be resistant to adverse culture conditions, which means the cells should have some anti - apoptosis property ; if not cultured i n suspension, the cells should also be able to grow in adherence

    一株成功的工程細胞除了要求目的蛋白的表達量高外，還必須適應無血清培養基培養；必須具有對不利環境的抵抗能力，即抗凋亡能力；對于非直接懸浮培養的細胞，還必須具備在無血清培養條件下的貼壁能力。
  4. However, the drawbacks of mammalian cell expression systems are apparent : they are difficult to culture in large scale, especially in serum - free medium ; the productivity is much lower than other expression systems and the costs are higher

    但哺乳動物細胞表達系統的缺點也很明顯，如表達量低、大規模培養困難、生產成本高昂等。
