中文摘要: |
参考GenBank 中鸭瘟病毒gI 基因序列设计并合成引物,以鸭瘟病毒河南分离株DNA 为模板进行PCR 扩增,将扩增片段克隆至PGEM-T 载体上,得到含gI基因重组质粒。经酶切鉴定,并对重组阳性质粒进行序列测定。结果表明,获得的片段含鸭瘟病毒gI 基因,全长1 089 bp,与已报道的其他疱疹病毒gI 基因具有较高的同源性,编码432 个氨基酸,蛋白分子质量为39.7ku、等电点(PI)为6.06。 |
英文摘要: |
According to published duck plague virus (DPV)gI gene sequences, a pair of specific primers was designed and synthesized. The genomic DNA of DPV Henan strain, which was isolated from Henan, was used as template.The PCR product cloned into the PGEM-T vector. The gene was sequenced and a complete open reading frame was found by bioinformatics tools of ORF Finder and Blastn. Bioinformatics analysis showed that the ORF of 1 089 bp encoding gI gene and encoding 362 amino acids was obtained. The protein molecular weight was 39.7 ku,and its isoelectric point PI was 6.060. |
