摘要:

目的: 探讨杜氏利什曼原虫39 kDa抗原基因的结构。方法: 将表达杜氏利什曼原虫39kDa 抗原肽段的重组噬菌体中插入DNA片段亚克隆人质粒载体pUC18中, 并对插入片段进行限制性内切酶谱分析。结果: 插入片段大小近1.3 kb, 其3’端含有单一的kpnⅠ、XbaⅠ、HincⅡ和PstⅠ识别位点, 表明该片段为一非重复序列结构。

关键词: 杜氏利什曼原虫, 抗原基因

Abstract:

AIM: To characterize the L. donovani gene encoding 39 kDa antigen. METHODS: The recombinant phage DNA fragment expressing 39 kDa antigen of L. donovani was subcloned in to pUC18 vector and further analyzed by restriction endonuclease digestion. RESULTS: The size of the inserted fragment was nearly 1.3 kb with a single site recognized by Kpn I, Xba I, HincⅡ and Pst I respectively at the 3’-end of the fragment. CONCLUSION: The inserted fragment might be a single copy containing only one reading frame and one non-encoding region.

Key words: Leishmania donovani, antigen, gene.
