分离原代细胞初期,为了避免造成污染,一般会建议预防性加入适量双抗或者三抗。多加抗生素对细胞无益,可以在细胞培养稳定后降低用量或不加抗生素。已知抗生素对细胞有不同影响,如下表所示:
Antibiotics | Cyto effect |
Beta-lactam antibioticsβ- 内 酰 胺(penicillin) | Alteration in protein synthesis Inhibition of cell proliferation |
Aminoglycosides 氨基糖甙类(streptomycin,anamycin, gentamycin) | Reduction of protein synthesis DecreasedATP levels Cytotoxicity |
Polyene macrolides 环内酯类(amphotericinB/fungizone, nystatin) | Cell membrane disturbance Cytotoxicity |
