Abstract: The prokaryotic expression plasmid of hygromycin-B-phosphotransferase(HPT) was constructed. The hpt gene was cloned by PCR. It was digested by SalⅠ/NotⅠand subcloned into expression vector pET-28b(+). pET-28b-hpt was transferred into E. coli Rosset; fusion protein was induced by isopropyl-β-D-thiogalactopyranoside (IPTG) and analyzed by SDS-PAGE. The most products existed in an inclusion body form. The HPT protein purified by Ni2+-NTA column was used to immunize New Zealand rabbits. The HPT polyclonal antibodies reveal high sensitivity and specificity.

Key words: hygromycin-B-phosphotransferas, prokaryotic expression, recombinant protein, polyclonal antibodies
