| Background | In most cases, once pneumococcal pneumonia has been identified, doctors will prescribe antibiotics. These antibiotic usually help alleviate and eliminate symptoms between 12 and 36 hours after being taken. Despite most antibiotics' effectiveness in treating the disease, sometimes the bacteria can resist the antibiotics, causing symptoms to worsen. Additionally, age and health of the infected patient can contribute to the effectiveness of the antibiotics. |
| Application | Immunogen, WB, ELISA |
CRM197相较于其他传统载体蛋白有几个显著优势: 安全性高:作为天然白喉毒素的无毒突变体,其安全性记录极佳,大规模使用中不良反应率低。 免疫原性强:能非常有效地刺激辅助T细胞,产生强大的免疫增强效果。 无预存免疫干扰:在婴幼儿中,对白喉毒素/CRM197的预存抗体水平通常很低。相比之下,使用TT或DT作为载体时,母亲传给的抗体或婴儿常规接种的百白破疫苗可能产生预存抗体,理论上可能干扰新结合疫苗的免疫效果。CRM197在一定程度上避免了这种潜在干扰。 工艺成熟:其重组生产技术成熟稳定,易于实现大规模、高纯度的生产。
