| 生化机理 | 作用方式：该ß-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：ß-内酰胺酶切开氨苄青霉素的ß-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)。 |
一般描述
应用
建议以 100mg/L 的抗菌用量用于细胞培养基中。建议以 20-125μg/ml 的量用于氨苄西林抗性研究。在 37°C 下可稳定 3 天。
Description
Chemical structure: ß-lactamAmpicillin is a semi-synthetic derivative of penicillin that functions as a broad-spectrum antibiotic. It has been used to study antibiotic resistance and penetration limitations, the synergy between multiple antibiotics, certain bloodstream infections, and has been used to develop PCR assays to detect resistance genes in cerebrospinal fluid.Recommended for antibacterial use in cell culture media at 100 mg/L.Recommended for use in ampicillin-resistance studies at 20-125 μg/ml.
Preparation instructions
Ampicillin is reported as slightly soluble in water, practically insoluble in alcohol, chloroform, ether and fixed oils but soluble in dilute acids or bases. The solution should not be autoclaved; a stock solution should be sterilized through filtration and stored frozen, where it will be stable for months.
