摘要
目的构建突触后致密物质-95(PSD-95)结构域PDZ1腺病毒重组体。方法以异硫酸氢胍-酚-氯仿一步法提取的总RNA为模板,采用反转录PCR(RT-PCR)法获得PDZ1的cDNA;与腺病毒穿梭载体用T4DNA连接酶连接;连接产物转化大肠杆菌JM109进行筛选、序列测定。结果①提取到未降解的总RNA;②经RT-PCR得到了PDZ1的cDNA;③酶切鉴定能观察到PDZ1和pAdTrack-CMV两条带;④PDZ1测序图谱与文献报道完全一致。结论获得了含目的基因PDZ1的腺病毒穿梭载体重组体。
Objective To construct recombinant pAdTrack- CMV - PDZ1. Methods Using the total RNA extracted from fresh rat hippocampns as template, the cDNA of PDZ1 was amplified by RT - PCR; the cDNA obtained was subsequently cloned into the shuttle vector pAdTrack-CMV (CLONTECH), and then, the sequence of the product was determined. Results ① Total RNA was obtained. ②The cDNA of PDZ1 was amplified by RT - PCR. ③The recombinant was found containing two bands of pAdTrack - CMV/PDZ1 by restriction enzyme digestion. ④The sequence of cloned PDZ1 was identical with that report- ed in GenBank. Conclusion Recombinant of pAdTrack- CMV- PDZ1 is obtained.
