| 摘 要： | 为获得抗青海血蜱免疫原基因，用免抗青海血蜱差异蛋白阳性血清和兔抗青海血蜱唾液蛋白阳性血清对青海血蜱cDNA表达文库进行了免疫学筛选，经过初筛和复筛共获得58个阳性信号。用所得阳性噬菌体转染宿主菌BM25．8使之自动亚克隆为重组质粒，用此亚克隆质粒转化宿主菌JM109并从中提取重组质粒进行PCR、酶切和测序分析。序列分析表明：共获得新cDNA序列21个。将前5个cDNA登录GenBank／ncbi，获取登录号。所获阳性克隆为青海血蜱保护性抗原的筛选奠定了基础。 |

| Abstract: | To obtain the immunogen against Haemaphysalis qinghaiensis,a cDNA expression library of H.qinghaiensis was screened with rabbit anti-H.qinghaiensis differential protein serum and rabbit anti-H.qinghaiensis saliva protein serum.Totally 58 positive signals were obtained.Pure phage stocks were harvested by plaque purification and converted to plasmid subclones by plating phage on host strain BM25.8.Recombinant plasmids that were subcloned in BM25.8 were isolated and then transformed into host strain JM109.Twenty one positive new clones were obtained after analysis of plasmids abstracted from JM109 by PCR,restriction digestion and sequencing.Five of the new clones were submitted to the GenBank/DDBJ/EMEL nucleotide sequence database. |
