摘要 目的:构建稳定表达猪PBD-1的转基因细胞系,为稳定生产猪PBD-1并将其应用于新型兽药的开发提供生产细胞源。方法:真核表达载体pIRES2-EGFP-PBD-1经酶切和测序鉴定后,用脂质体介导法转染marc-145细胞,通过不同浓度的G418加压筛选,和进一步采用单个克隆法筛选,建立稳定转染的marc-145细胞系,用RT-PCR及抑菌试验检测PBD-1的表达。结果:建立了稳定转染的marc-145细胞系,成功地表达目的基因,其培养上清液及细胞冻融液具有抑菌作用。结论:利用真核表达载体pIRES2-EGFP-PBD-1稳定转染marc-145细胞系,为进一步研究猪PBD-1的生物学特性及其在兽用生物制品上的应用奠定了基础。
