产品名称：硫酸庆大霉素溶液
产品货号：QN0090
产品规格：10mL

本品具有很好热稳定的氨基糖苷类抗生素。庆大霉素作用原理在于与细菌核糖体亚基的L6蛋白结合，抑制细菌蛋白质合成。临床上，主要用于治疗多种细菌感染，尤其适用于革兰氏阴性菌。

浓度：50mg/ml
储存条件：-20℃避光

硫酸庆大霉素(Gentamicin sulfate salt)是一种广谱氨基糖苷类抗生素，对大量革兰阴性细菌及革兰阳性菌都有良好抗菌能力，甚至包括某些β-内酰胺敏感的抗万古霉素(VRE)肠球菌，和耐糖肽抗生素的一些“超级细菌”。其抑菌机理在于通过与细菌核糖体30S亚基结合导致密码子错误，阻断肽酰-tRNA从A位点到P位点的转运，从而抑制细菌蛋白质的合成。

硫酸庆大霉素在实验室中应用非常普遍：1)微生物学研究，常用于药敏实验筛选敏感性细菌;2)细胞培养内抑制细菌污染，有效浓度为 0.5 -50 µg/mL;3)分子生物学研究，常用来选择性筛选携带庆大霉素抗性基因的阳性克隆，常用使用浓度15 µg/ml。

产品说明：
Mitomycin C is produced by a strain of actinomyces named Streptomyces caespitosus. The structural formula of Mitomycin C is a combination of three of the representative anticancerous radicals, quinone, urethane and aziridine group. It is supplied in a vial containing 2 mg Mitomycin C，The other In-active ingredient in Mitomycin-C is Sodium Chloride.
Mitomycin C is widely used among the Mitomycin group of antibiotics because it is the least toxic and with the most potent antitumor activity. It has extraordinarily strong activity against Ehrlich ascites tumor cell.It also possesses strong bactericidal action against gram-positive and gram-negative organisms.
Mitomycin C inhibits DNA synthesis. It reacts covalently with DNA, in vivo and in vitro, forming cross-links between the complementary strands of DNA. This interaction prevents the separation of the complementary DNA strand, thus inhibiting DNA replication. Mitomycin C is one of the few antibiotics known to interact with DNA in this fashion.
The recommended concentration for eukaryote cell culture use is 10-50 µg/mL.
Preparation Instructions
Mitomycin C is soluble in water.The solubility at 0.5 mg/mL (1 vial/4 mL) in water yields a clear blue solution. The contents of one vial dissolved in 4 mL water produces a solution that is 1.5mM Mitomycin C. A 0.5% solution in water has a pH of 6.0-7.5.A saturated solution has a pH of 5.0-9.0.
Mitomycin C undergoes rapid degradation in acidic solutions (pH less than 6.0). It is most stable in aqueous solutions at pH 6-9. Generally, solutions at pH 6-9 can be stored at 0-5℃ for up to a week. If a precipitate forms, a fresh solution should be prepared. The precipitated solution has proven to be toxic to cells. Stock solutions should also be stored in the dark since it is readily decomposed by light.
A study has shown that the amount of Mitomycin C in a culture medium (at 38℃) containing antibiotics with fetal calf serum was reduced by 29% after 30 minutes and by 53% after 60 minutes.
