| Abstract: | The protein coded by the full-length cDNA sequence of ran gene from color crucian carp(Carassius auratus gibelio)expressed in E.coli was separated and purified by SDS-PAGE in our study.Moreover,the expressed protein was applied to immunize rabbits and corresponding multiclonal antibody was prepared.Western blotting results indicated that the prepared antibody had the high titer(1∶1000)and high specificity.Moreover,the keys of this technique including the relative molecular mass of antigen,the quantity of proteins in each injection,procedure of injection,and approaches of injection were also introduced in this paper. |
