嵌合

So it can be essential momitoringindex of colon carcinoma and its tumor specificness is apply by manygene therapy of tumor. Transcriptional regulatory element of CEAcontains enhancer element and promotor in the 5th flanking region whichcan control expression of objective gene in positive cancer tissue of CEA. Objectives: To explore the joint promoter with high activity,consisting CEA promotor and CMV enhanser.

The involvement of oxidization of peroxid in the antigen-antibody reaction makes the cell membrane permeability enhanced, so the fluorescence-labeled antibody stain can infiltrate into the cell easily and contact the antigen rapidly and diffusely, and then the antigen-antibody crosslinking can be formed efficiently.

利用过氧化氢的氧化作用参与抗原抗体反应，使细胞的膜通透性增强，利于荧光标记抗体染液渗入，从而更快速、广泛地接触抗原，更有效的抗原抗体的嵌合交联。

Necropsies were performed at 21 days post-challenge, the lymph nodes in the nonvaccinated but challenged pigs were larger than those of vaccinated pigs. The PCV2 genomic copy loads in lymph nodes were reduced in vaccinated pigs. Moderate amounts of PCV2 antigen were detected in most lymphoid tissues of nonvaccinated pigs. These data indicated that when given intramuscularly in pigs, the chimeric PCV1-2 live virus and recombinant plasmid induces protective immunity against PCV2 infection and could potentially serve as an effective vaccine.

攻毒后21天攻毒对照组猪淋巴结比免疫组猪显著肿大，免疫组猪血清、淋巴结中PCV2病毒载量低于对照组，攻毒对照组猪淋巴结中PCV2抗原含量高于免疫组，这些结果表明嵌合型猪圆环病毒PCV1-2及真核表达质粒肌肉注射免疫商品猪后，对PCV2感染能产生保护性免疫应答，有可能成为候选疫苗。
