杀稻瘟菌素 S 无菌溶液 MCE Blasticidin S, Sterile 来源于灰色链霉菌（Streptomyces griseochromogenes），是一种核苷类抗生素，主要通过干扰核糖体中肽键的形成而特异性抑制原核细胞或真核细胞的蛋白合成。 产品来源： https://www.medchemexpress.cn/inhibitor-kit/blasticidin-s-sterile.html Description & Advantages: Blasticidin S is a peptidyl nucleoside antibiotic isolated from Streptomyces griseochromogenes. It acts by blocking hydrolysis of peptidyl-tRNA induced by release factors and inhibits peptide bond formation. It can be used as a selection agent in both mammalian cells and bacterial cells. Resistance to Blasticidin S is conferred by bsr and BSD. Therefore, Blasticidin S is a popular and effective antibiotic for selecting vectors bearing the bsr or BSD gene in mammalian cell lines. The recommended working concentration ranges from 1 to 20 μg/mL depending on the cell line and 50–100 μg/mL for bacterial selection. For bacterial selection purposes, the salt content of the LB medium must remain low ( 品牌介绍: MCE (MedChemExpress) 拥有数百种全球独家化合物，我们致力于为全球科研客户提供最新最全的高品质小分子活性化合物；10,000 多种高选择性抑制剂、激动剂涉及各热门信号通路及疾病领域；设有专业的实验中心和严格的质控、验证体系；提供 LC/MS、NMR、HPLC、手性分析、元素分析等各项质检报告，确保产品的高纯度、高品质；产品的生物活性多经各国客户实验验证；Nature, Cell, Science 等多种顶级期刊及制药专利收录了MCE客户的科研成果；专业团队跟踪最新的制药及生命科学研究进展，为您提供全球最新的活性化合物；与世界各大制药公司及知名科研机构建立了长期的合作。
