Analysis Note USP potency testing is carried out on control vials after γ-irradiation to assure full biological activity (except where noted). Application Recommended for use in molecular biology applications at 20-50 μg/ml. Biochem/physiol Actions β-内酰胺类抗生素,具有连接到青霉素结构上的氨基侧链。青霉素衍生物,通过灭活细菌细胞膜内表面上的转肽酶,抑制细菌细胞壁的合成(肽聚糖交联)。仅对生长的 Escherichia coli 具有杀菌作用。抗性方式:通过 β-内酰胺酶使氨苄西林的 β-内酰胺环分裂。抗菌谱:革兰氏阴性和革兰氏阳性细菌。 Reconstitution Prepare stock solutions directly in the vial at any concentration in the recommended range. Stock solutions should be stored at -20 °C. Stable at 37 °C for 3 days. Protocols & Applications Antibiotic Selector for application, solubility, solution stability, working concentration, and mode of action information
