COA 产品使用指南

Clindamycin 是一种具有口服活性的广谱抑菌林可酰胺类抗生素 (antibiotic)。Clindamycin 有效抑制细菌蛋白质合成,其具有以亚抑制浓度 (sub-MICs) 在金黄色葡萄球菌中毒力因子表达的能力。Clindamycin 的抗性是由 50S 核糖体亚基 (23S rRNA) 中抗生素结合位点的酶促甲基化产生。Clindamycin 降低杀白细胞毒素 (PVL),毒性休克-葡萄球菌毒素 (TSST-1) 或 α-溶血素 (Hla) 的产生。Clindamycin 也可用于疟疾的研究。

生物活性

Clindamycin is an orally active and broad-spectrum bacteriostatic lincosamide antibiotic. Clindamycin can inhibit bacterial protein synthesis, possessing the ability to suppress the expression of virulence factors in Staphylococcus aureus at sub-inhibitory concentrations (sub-MICs). Clindamycin resistance results from enzymatic methylation of the antibiotic binding site in the 50S ribosomal subunit (23S rRNA). Clindamycin decreases the production of Panton-Valentine leucocidin (PVL), toxic-shock-staphylococcal toxin (TSST-1) or alpha-haemolysin (Hla). Clindamycin also can be used for researching malaria[1][2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
