1. E. coli antigen complex, can be divided into cell antigen (O), flagella antigen (H) and surface antigen (K), which has swallowed up body resistance and anti-complement the capacity. 大肠杆菌的抗原成分复杂，可分为菌体抗原（O）、鞭毛抗原（H）和表面抗原（K），后者有抗机体吞噬和抗补体的能力。
2. It can be used for studying adsorption kinetics of biomolecules and detecting complex layer of antigen-antibody when antibody (or antigen) combined with antigen (or antibody) coated on solid surfaces. 它不仅能够大面积精确显示超薄膜的厚度分布，而且能够用于表面实时吸附的动力学研究。
3. Result evids that it is venenous. The immunogenicity of antigen from liquid culture outweighs antigen from solid. 用两菌株制备的液体抗原比固体抗原的免疫原性强。
4. I tried a lot many years ago, try to seroconvert from e antigen withe antigen positive, so in that case you should be able to use interferon. 几年以前我就做了很多尝试，使HBeAg（+）的患者发生血清转换，在这种情况下，应该使用干扰素。
5. Emulsions also protect the antigen form a rapid degradation by enzymes and could modify the electric charge of the antigen becoming then, more immunogenic. 乳剂同样用生化酶保护抗原防止其极度退化，并且可以将抗原的导电电荷改善得更能产生免疫性。
