摘要: Promoter activities were examined by comparing combinations of promoters and enhancers derived from various genes. A hybrid promoter comprising a combination CMV enhancer mammalian β-actin promoter, or the post-transcriptional regulatory region genomic sequence Woodchuck Hepatitis Virus (WPRE) was found to be stronger than existing promoters. Furthermore, could enhanced coexpressing oncogene product Ras, which is transactivator.
