Ampicillin trihydrate
CAS No. : 7177-48-2
MCE 国际站：Ampicillin trihydrate
产品活性：Ampicillin trihydrate (D-(-)-α-Aminobenzylpenicillin trihydrate) 是一种广谱 β-内酰胺类抗生素，可对抗多种革兰氏阳性和革兰氏阴性细菌。
研究领域：Anti-infection
作用靶点：Bacterial | Antibiotic
In Vitro: Ampicillin trihydrate (D-(-)-α-Aminobenzylpenicillin trihydrate) inhibits the growth of E. coli of swine origin in a dose-dependent manner. The effective inhibitory concentration of Ampicillin trihydrate is 2.5 uG/mL.
In Vivo: Ampicillin trihydrate (D-(-)-α-Aminobenzylpenicillin trihydrate) is very effective in alleviating the symptoms of hemorrhagic enteritis in a 11-week old pig.
Ampicillin trihydrate produces maximum concentrations in bile twice as high as in serum. The peak concentration of ampicillin after an oral dose is as twice as high in portal blood as in peripheral blood.
Ampicillin trihydrate provides neuroprotection against ischemia-reperfusion brain injury. Ampicillin trihydrate reduces the activities of MMPs and increases the expression level of GLT-1. Pretreatment with Ampicillin trihydrate significantly reduces medial hippocampal cell death following global forebrain ischemia.

文献和实验Ampicillin (50mg/ml) Ampicillin Dissolve Ampicillin (Na salt from Sigma, A-9518) in H2 0. Store 1 ml aliquots at 20o C in common freezer for stock solutions 上一篇：PREPARATION
Preparing Antibiotics Stock Solution and Ampicillin Agar Plates
AMPICILLIN Beta-lactam-antibiotics are not very stable when dissolved. Slow but steady degradation happens even when frozen to -20°C. Therefore commercial beta-lactam-antibiotics are sold as dried powder and reconstituted
青霉素浓缩法（ampicillin enriching technique）
利用青霉素特异性地杀死野生型细胞、保留营养缺陷型细胞的方法。青霉素能抑制细菌细胞壁的合成，所以只能杀死生长繁殖中的细菌，而不能杀死停止分裂的细菌。在只能使野生型生长而不能使突变型生长的选择性液体培养基中，野生型被青霉素杀死，而突变型则不被杀死，从而淘汰野生型，使突变型得以浓缩。可适用于细菌和放线菌，是营养缺陷型突变体筛选的常用方法之一。
