摘 要: 目的构建和鉴定大肠杆菌poly(A)化mRNA的cDNA文库。方法应用限制性显示PCR技术构建大肠杆菌poly(A)化mRNA的cDNA文库,筛选、收集cDNA片段,并进行测序。根据测序结果进行初步的生物信息学分析和结果验证。结果构建了大肠杆菌poly(A)化mRNA的限制性cDNA文库,并对其中66个基因片段进行了分析。结论所构建的大肠杆菌poly(A)化mRNA的cDNA文库片段重复性低,质量高。 Objective To construct and identify th e cDNA library of E.coli mRNA with poly(A) tracts. Methods The cDNA library of E .coli was constructed by restriction display-PCR (RD-PCR) technique, followed by sequencing and bioinformatics analyses. Results cDNA library of E.coli mRNA w ith poly(A) tracts was successfully constructed, and 66 gene fragments were seq uenced. Conclusion The constructed cDNA library of E.coli mRNA with poly(A) tra cts contains alow rate of repeti-tion and is of high quality.
