摘要：
Human epiregulin cDNA was amplified from the lung cancer cell line A549 using RT-PCR. After adding 6 His codon to its 3' end, it was cloned into a high efficient secretive Escherichia coli system with alkaline phosphatase promoter( phoA promoter)constructed in our lab and induced for expression. The product was purified one-step by Ni-NTA column. Amino acid sequence analysis revealed the identity of our product with that previously reported. The product showed strong proliferative effect on fibroblast cell line Balb/c3T3 and growth inhibitory effect on epithelial carcinoma cell line A431.
