文摘The fusion gene of BPI 23 and human Fcγ1 was obtained by PCR method,and the expression plasmid was constructed to express recombinant BPI 23 \|Fcγ1 fusion protein in CHO cells.After transfection with the plasmid and selection by methotrexate,the cell lines expressing the fusion protein were obtained.The recombinant protein was purified using cation\|exchange chromatography and its bioactivity was proved with bactericidal assays.
