摘要:

利用转基因小球藻为生物反应器生产兔防御素NP-1蛋白具有重要的应用价值。本研究利用椭圆小球藻(Chlorella ellipsoidea)硝酸还原酶(nitrate reductase)缺失突变体为受体, 构建了包含NPTII基因和硝酸还原酶基因两个筛选标记的兔防御素蛋白表达载体, 采用电激法将目的基因转入椭圆小球藻硝酸还原酶缺失突变体nrm-4, 获得了正确表达防御素蛋白的转基因藻, 从而表明通过硝酸还原酶作为筛选标记基因并结合硝酸还原酶缺失突变体可作为较好的小球藻生物反应器生产模式。

Abstract:

Application of transgenic Cholrella as bioreactor to express rabbit neutrophile pepetide-1 (NP-1) shows great practical value. In this paper, an NP-1 expression vector containing two selective marker genes NPTII and nitrate reductase gene was constructed. The NP-1 gene was transformed into the nitrate reductase-deficient mutant nrm-4 of Chlorella ellipsoidea via electroporation, and the transgenic alga expressed the active NP-1 were obtained.
