More information about their structure and function relationship will be meaningful in understanding the molecular mechanism of ion pump and conformation alteration during ion transport and sensory transduction. In this paper, we report screening strains from samples collected from Ebi lake and Altun moutain Aqik lake, Xinjiang Province, and got 60 clonies from them. We choose 8 of them for further investigation and confirmed that they all belong to the Halobacteriaceae genus and through comparasion of several minute diffrerence medium we had the optimal medium for their growth.. Through this procedure we had established a set of methods for screening clonies from wild environment.and isolation and purification of these archaerhodopsin. Furthermore we used PCR method to identify their DNA sequence.

The ELISA titre was 1:2000.By cell fusion, 46 hybridoma cell lines were screened,and 10 lines were cloned with limited dilution method.16 lines secreting anti-bFGF monoclonal antibody were been developed, and 2 lines targeted fusion protein. Sensitive ELISA and dot-ELISA for bFGF was developed with this mAb. The detection limit of them were 0.1 ng/well and 0.5 ng/well. The expression level of anti-bFGF mAb by different rebuilt engineering cells were identified by western blot and to direct rebuild recombiment engineering cell. The dose and character of anti-bFGF mAb inhibiting bFGF biology activity were searched by 3T3 cell line. Searching 20 tissue of liver cancer, liver cancer cell lines and general tissue of liver, finding bFGF were highly expressed in tissues of liver cancer and liver cancer cell lines. Affinity chromatography purifying bFGF was set up by mAb binging CNBr-pepharose 4B, and the purification was 95%. We found that the titer of anti-bFGF antibody was very high in serum of neuropathic amyotrophia.
