Product Introduction:
This product is the levofloxacin, and its antibacterial activity in vitro is about twice that of ofloxacin. Its mechanism of action is to prevent the synthesis and replication of bacterial DNA by inhibiting the activity of bacterial DNA rotase, which leads to bacterial death (for reference only).
Use and synthesis method:
Use: scientific research reagent, widely used in molecular biology, pharmacology and other scientific research. This product has a broad spectrum antibacterial action, antibacterial action is strong, and has strong antibacterial activity against most enterobacteriaceae bacteria, such as Escherichia coli, Klebsiella, Proteus, Salmonella, Shigella and Haemophilus influenzae, Legionella pneumophila, Neisseria gonorrhoea and other gram-negative bacteria. It also has antibacterial effect on Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes and other gram-positive bacteria, mycoplasma pneumoniae and chlamydia pneumoniae, but it has poor effect on anaerobic bacteria and enterococcus.
Physical shape:
Melting point 214-216℃
Solubility:
Soluble in glacial acetic acid, slightly soluble in 0.1mol/L hydrochloric acid solution, insoluble in ethanol, insoluble in ether

请问怎样配制左氧氟沙星无菌溶液 2022-07-25 11:01:33
Administrator您好，试剂粉末不是无菌的，如果实验要求无菌溶解后通过过滤的方法除菌，0.22微米孔径的滤膜过滤。
