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.

Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.

Methods Hepatoma carcinoma cells and pulmonary carcinoma cells were cultured in vitro, Mononuclear cells in healthy person's peripheral blood were collected. PBMCs were mixed with liver cancer and lung cancer cells by proportion, and enriched tumor cells by superparamagnetic nanoparticle antibody complex, lung cancer specificness was identified by fluorescence nanocrystals bioprobe. We smeared tumor cells on glass slide and identified pulmonary carcinoma cells specfficity by fluorescence nanocrystals bioprobe.

Because ouabain polyclonal antibody made blood pressure reduced for shorter time and possessed slightly allergy, we aimed to prepare a new depressor, ScFv, with high specificness by advanced phage display technique. The heavy-chain and kappa light-chain variable region gene repertoir of immunoglobin were amplified individually with heavy chain and light chain primers of Pharmacia Corporation and assembled into ScFv by a linker with overlap extension PCR.
