根据Genβank发表的序列,应用DNAstart分析软件设计并合成一对引物用于扩增水貂β干扰素(IFN—β)基因,从病死水貂的脾脏中提取总RNA,RT—PCR扩增水貂β干扰素基因,获得了约561bp片段,将其克隆到pEasy—T1载体中,进行序列分析,证实该基因是水貂β干扰素基因。将测序结果与GenBank发表的雪貂(EF581890.1)的IFN—β基因序列进行比较,核苷酸序列同源性为100.0%,氨基酸同源性为100.0%。同时将核苷酸序列、氨基酸序列与其他几种犬科动物进行遗传进化分析,其同源性分别在83.0%~100.0%之间和69.4%~100.0%之间。
根據Genβank髮錶的序列,應用DNAstart分析軟件設計併閤成一對引物用于擴增水貂β榦擾素(IFN—β)基因,從病死水貂的脾髒中提取總RNA,RT—PCR擴增水貂β榦擾素基因,穫得瞭約561bp片段,將其剋隆到pEasy—T1載體中,進行序列分析,證實該基因是水貂β榦擾素基因。將測序結果與GenBank髮錶的雪貂(EF581890.1)的IFN—β基因序列進行比較,覈苷痠序列同源性為100.0%,氨基痠同源性為100.0%。同時將覈苷痠序列、氨基痠序列與其他幾種犬科動物進行遺傳進化分析,其同源性分彆在83.0%~100.0%之間和69.4%~100.0%之間。

According to published GenBank sequences, a primer for the increase of mink β - interferon ( IFN - beta) gene was designed and synthesized by DNAstart analysis software, total RNA was extracted from the infected mink spleen, mink β - interferon gene was increased about 561 bp through RT - PCR method. After this gene was cloned to pEasy - T1 carrier, the facts prove that this gene is mink β - interferon according sequence analysis. The result suggests that β - interferon nucleotide sequence homology are 100.0% and amino acid homology are also 100.0% when compared sequence result with published gene sequence(EF581890.1 ) from GenBank. The nucleotide sequence homology and amino acid homology are 83.0% - 100.0% and 69.4% - 100.0% respectively when compared with another canine animals.
