Oxytetracycline works by interfering with the ability of bacteria to produce essential proteins. Without these proteins, the bacteria cannot grow, multiply and increase in numbers. Oxytetracycline therefore stops the spread of the infection and the remaining bacteria are killed by the immune system or eventually die. Oxytetracycline is a broad-spectrum antibiotic, active against a wide variety of bacteria. However, some strains of bacteria have developed resistance to this antibiotic, which has reduced its effectiveness for treating some types of infections. 供应商信息 DC Chemicals Limited 认证状态: 已认证供应商 商品数: 20124件 电话: 58447131 地址: 浦东新区金豫路100号 地区: 上海市 上海市 浦东新区 联系人: Tony Cao 联系人电话: 862158447131 邮件: sales@dcchemicals.com 网址: www.dcchemicals.com 年贸易额: >1000万 D&C Chemicals provides a wide range of research chemicals and biochemicals including novel life-science reagents, reference compounds, APIs and Natural compounds for laboratory and scientific use.
