The ferritin gene was cloned from human genome using the PCR technology. After digested by the enzymes （BamH I, Sma I）, it was inserted into the plasmid pGEX-4T-2 to reconstruct the expression vector. Then the reconstructed plasmid was converted into E. coli whereby to confirm using the colony PCR, the enzyme digestion and the DNA sequencing. The recombinant protein was expressed after inducing by IPTG and then purified using urea for antibody preparation.
