青霉素起初是从真菌青霉菌中提纯制成,其作用机制为直接干扰细菌细胞壁的合成以及间接通过触发酶释放来进一步改变细胞壁。链霉素起初是从灰色链霉菌中提纯制成。其作用机制为与细菌核糖体的 30S 亚单位结合,进而抑制蛋白合成,导致敏感细菌死亡。两性霉素 B 是一种抗真菌剂,可通过提高真菌质膜透性来抑制真菌和酵母菌的生长。
Can I use antibiotics such as Pen-Strep or Antibiotic-Antimycotic (100X) when culturing Sf9 insect cells?
Yes, however, we do not recommend adding antibiotics to the medium at the time of thawing. Thaw cells into medium without antibiotic and allow the cells to recover from the thawing process. After that, you can add antibiotics by diluting into the medium.
