说明：配制组织培养基。

氯霉素，英文名称Chloramphenicol，一种细菌性广谱抗生素，可在肽键转移酶催化形成肽键的过程中抑制50S核糖体上mRNA的翻译，从而抑制革兰氏阴性和革兰氏阳性细菌的生长。此外氯霉素还具有立克次体属微生物抗性以及鹦鹉热-淋巴肉芽肿类衣原体抗性等，因此氯霉素可用于细菌筛选。对氯霉素乙酰转移酶基因（即CAT gene）进行乙酰化可抵制氯霉素的抗性。基于该原理，分子生物学实验中，氯霉素可作为一种筛选药物用于筛选含有氯霉素抗性基因的转化细胞。

推荐有效工作浓度为5-20µg/ml。

储存液制备：

称取1g氯霉素溶于20ml 100%乙醇充分溶解后得到50mg/ml的母液，0.22µM有机相滤膜过滤除菌后，分装成小量后-20°C冻存，避免反复冻融，一年有效。

【注】：氯霉素储存液不可高压灭菌。

注意事项:

(1)用于细胞实验，溶解后，须用一次性针头滤器过滤除菌。

(2)为了您的安全和健康，请穿实验服并戴一次性手套操作。
