摘要: 根据NCBI上提供的NP24 基因(GenBank 登录号为543979)的序列,设计全长引物,扩增编码区cDNA,通过克隆至中间载体pMD18-T,将类甜蛋白基因NP24 插入植物表达载体PBI121,构建超表达载体PBI121-NP24,采用CaCl2冻融法将其转入农杆菌EHA105 菌株中。酶切鉴定表明,目的基因已经正确地插入到PBI121载体中,超表达载体构建成功。菌液PCR鉴定,超表达载体已转入农杆菌中。

Abstract: According to the sequence of NP24 gene (GenBank registration number 543979) in NCBI, we designed primers and amplified cDNA encoding area. Then the cDNA was cloned to intermediate carrier pMD18-T. We built the over-expression vector PBI121-NP24 by inserting the gene NP24 into plant expression vector PBI121. The over-expression vector PBI121-NP24 was transferred into agrobacterium EHA105 by the CaCl2 freeze-thaw method. Enzyme identification showed that the gene had been correctly inserted into the PBI121 carrier and the over-expression vector was built successfully. Microbial PCR identification proved that the over-expression vector had been transferred into agrobacterium.
