抗生素
- 細胞庫之細胞培養基不加抗生素
- 培養自ATCC引進之細胞株,培養基中不加抗生素。
- 培養自其他實驗室引進之細胞株,製作token freeze前培養基須添加抗生素,待token freeze通過污染測試後,大量培養時則不加抗生素。
- 寄送活細胞時,須將培養液充滿整個flask時,則須添加抗生素 (penicillin 100 units/ml + streptomycin 100ug/ml)。
- 若要檢測mycoplasma,則培養基內不可添加gentamicin,因gentamicin會抑制mycoplasma生長。
- 去除細菌污染之抗生素混合配方:penicillin 250 units/ml, streptomycin 250 ug/ml, neomycin 250 ug/ml, bacitracin 2.5 units/ml,注意混合使用後藥物毒性會增強。
- 抗生素使用種類與濃度:
