General description

氨苄西林钠盐是超广谱β-内酰胺家族成员,是青霉素的半合成衍生物,具有广谱抗生素的作用。该β-内酰胺抗生素通过与青霉素结合蛋白(PBP)结合抑制细胞壁关键组分肽聚糖的合成,从而抑制细胞壁合成。氨苄西林钠盐具有抗多种革兰氏阳性菌和革兰氏阴性菌活性,包括大肠杆菌(E. coli)、β-内酰胺敏感VRE、耐万古霉素肠球菌(VRE)、金黄色葡萄球菌(Staphylococcus aureus)和肺炎链球菌(Streptococcus pneumoniae)。常被研究型实验室用于研究抗生素的耐药性和渗透性限制、多种抗生素之间的协同作用、大肠杆菌重组质粒的筛选和维持。

Application

氨苄西林钠盐已用于:
  • 突变和转化细胞的氨苄西林抗性筛选

Biochem/physiol Actions

作用方式:该β-内酰胺抗生素通过灭活位于细菌的细胞膜内表面的转肽酶从而抑制细菌细胞壁合成。

耐药性机制:β-内酰胺酶切开氨苄青霉素的β-内酰胺环,使其失去活性。

抗菌谱:包括革兰氏阳性菌(类似青霉素)和革兰氏阴性菌(类似四环素和氯霉素)。

Features and Benefits

  • 高品质抗生素,适合各种研究用途
  • 适于细胞生物学和生物化学研究。

Preparation Note

密闭。干燥。上锁或放在只有合格或授权人员才能进入的地方
据报道,氨苄青霉素微溶于水,几乎不溶于酒精、氯仿、醚和固定油脂,但溶于稀酸或稀碱。 该溶液不应高压灭菌;原液应通过过滤消毒并冷冻保存,可稳定数月。

Other Notes

如需了解生化试剂系列的更多信息,请填写此表
将容器密封在干燥、通风良好的地方。储存类别(TRGS 510): 不可燃的固体

Disclaimer

据报道,该产品在25°C、43%和81%相对湿度下可稳定6周。 另外的研究表明氨苄青霉素在溶液中的稳定性与pH、温度和缓冲液的性质有关。 当储存在pH值7以上时,它的活性很快就会丧失。 推荐最佳保存条件为2-8℃,pH 3.8-5,一周内其活性可保留90%。

Antibiotics are often administered with antivenom following snakebite envenomings in order to avoid secondary bacterial infections. However, to this date, no studies have evaluated whether antibiotics may have undesirable potentiating effects on snake venom. Herein, we demonstrate that four commonly

Antibiotic combination therapies are important for the efficient treatment of many types of infections, including those caused by antibiotic-resistant pathogens. Combination treatment strategies are typically used under the assumption that synergies are conserved across species and strains, even though recent

Microbiota and intestinal epithelium restrict pathogen growth by rapid nutrient consumption. We investigated how pathogens circumvent this obstacle to colonize the host. Utilizing enteropathogenic E. coli (EPEC), we show that host-attached bacteria obtain nutrients from infected host cell in a process we

Recent observations have suggested that classic antibiotics kill bacteria by stimulating the formation of reactive oxygen species (ROS). If true, this notion might guide new strategies to improve antibiotic efficacy. In this study, the model was directly tested. Contrary to
