Even so , by truncating hbv pres gene , we finally obtained some useful " " bailors " , either nontoxic or self - activating , and used them to fish dna fragments of hbv pres interacting protein ( s ) from an ad vector constructed human embryonic cdna library

It concluded that self - activated luminescent centers are not distributed randomly but prefer to occupy the surface sites in nanoparticles . 5 . by raman spectra , epr spectra and uv irradiation - induced spectra change , the organic function groups of - oh , - ch3 and - coo adsorbed electrically on the surface of nanoparticles were discussed

In our work , different hbv pres gene fragments were amplified by pcr , cloned into pgbkt ? vector in yeast two - hybrid system 3 , and then transformed ah 109 yeast cells . the results showed that these pres expression products were nontoxic to yeast cells , but all self - activated the yeast two - hybrid system
