生化／生理作用
作用机制：氨苄西林是一种半合成的青霉素和ß-内酰胺抗生素，其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：对革兰氏阳性菌（类似于苄青霉素）和革兰氏阴性菌（类似于四环素和氯霉素）均有效。

注意
This product has been reported stable as supplied at 25°C at 43% and 81% relative humidity for six weeks. Additional studies have shown that the stability of Ampicillin in solution is a function of pH, temperature and the identity of the buffer. It′s activity is quickly lost when stored above pH 7. Optimal storage conditions are suggested as 2-8°C, and pH 3.8-5 where its activity was retained at 90%+ for a week.
準備報告
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.
分析報告
These products are for test and assay use only. They are not meant for administration to humans or animals and cannot be used to diagnose, treat, or cure diseases of any kind.
