一种常用于转染大肠杆菌潮霉素抗性基因的细胞选择抗生素。Hygromycin B is an aminoglycoside antibiotic substance naturally produced by Streptomyces hygroscopicus, which also shows anthelmintic activity. Hygromycin B has been shown to effectively inhibit translocation of mRNA and tRNAs on the ribosome in both bacteria and eukaryotes and also has a subtle effect on decoding fidelity as it slightly increases aminoacyl tRNA (A-site tRNA) affinity. Suitable for the selection of cells transfected with Escherichia coli hygromycin resistance gene (hyg or hph), as well as for the maintenance of the Hygromycin phenotype of resistant cells. Consistent with its more specific effect on translocation, hygromycin B exhibits monophasic inhibition of polypeptide synthesis, suggesting that it binds to a single site on the ribosome.
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液,使用的计算公式为:
开始浓度 x 开始体积 = 最终浓度 x 最终体积
