一般說明

化学结构:氨基糖苷类

應用

大观霉素是一种氨基环糖醇类抗生素,来源于 壮观链霉菌。它已被证明具有广泛的用途,包括治疗急性淋病性尿道炎和宫颈炎、标记细胞层以监测叶片发育期间的细胞命运、作为含有标记基因 Spcr 的植物相关转化系统中的选择标记、研究由 多杀性巴氏杆菌 溶血性曼氏杆菌 引起的牛呼吸道感染以及在 MS 琼脂培养基上产生质体编码 RNA 聚合酶缺乏的植物。大观霉素也可用于扩增携带低拷贝数的质粒。推荐在 7.5-20 mg/L 下用于细胞培养应用。

生化/生理作用

作用机制:壮观霉素通过与细菌30S核糖体亚基结合并干扰肽基tRNA易位而抑制蛋白质合成和延伸。

抗性机制:rpsE(核糖体蛋白S5的基因)突变可阻止壮观霉素的结合。氨基糖苷-3′-腺苷转移酶基因(aadA)也能使细菌产生抗性。

抗菌谱:壮观霉素能够对抗革兰氏阴性和革兰氏阳性菌。

注意

溶液可以在2-8°C下储存数周,或在-20°C下储存更长时间。

準備報告

制备储液时,应以10 mg/mL溶于水并过滤灭菌。

Noncoding RNAs (ncRNA) are widely expressed in both prokaryotes and eukaryotes. Eukaryotic ncRNAs are commonly micro- and small-interfering RNAs (18-25 nt) involved in posttranscriptional gene silencing, whereas prokaryotic ncRNAs vary in size and are involved in various aspects of gene

Gonorrhea may become untreatable, and new treatment options are essential. Verified resistance to spectinomycin is exceedingly rare. However, we describe a high-level spectinomycin-resistant (MIC, >1,024 μg/ml) Neisseria gonorrhoeae strain from Norway with a novel resistance mechanism. The resistance determinant was
