Ampicillin

半岛bd体育手机客户端 说明

一般描述

Chemical structure: ?-lactam
Ampicillin in a convenient ready-to-use solution useful in selecting for bacteria cells with specific resistance.

应用

Ampicillin is used to select bacteria cells with specific resistance during general microbiology studies. It is 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 .

生化/生理作用

A β-lactam antibiotic with an amino group side chain attached to the penicillin structure. Penicillin derivative that inhibits bacterial cell-wall synthesis (peptidoglycan cross-linking) by inactivating transpeptidases on the inner surface of the bacterial cell membrane. Bactericidal only to growingEscherichia coli.Mode of resistance: Cleavage of β-lactam ring of ampicillin by β-lactamase. Antimicrobial spectrum: Gram-negative and Gram-positive bacteria.

其他说明

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefullyresealed and kept upright to prevent leakage.
