The purpose of the studies is to design the recombinant virus SV 40 where the C-end of the basic structural protein of virus P-1 was replaced by a synthetic sequence of the neuropeptide bradykinin. The recombinant virus SV (SV 40/Brd) was obtained. In this virus 60 n.p. with 3'-end of VP-1 gene was substituted for 36 n.p. synthetic gene of bradykinin without impairing the frame of translation. The biological activity of SV 40 (Brd) was tested on the cultured cells CV-1 permissive for this virus. An immunofluorescence method was used to detect T antigen and to examine the cytopathic action of this recombinant. The gene engineering design does not make the recombinant loose its biological properties typical of wild virus.
这些研究的目的是设计重组病毒SV 40,其中病毒P-1基本结构蛋白的C端被神经肽缓激肽的合成序列所取代。获得了重组病毒SV(SV 40/Brd)。在这种病毒中,VP-1基因3'端的60个核苷酸被36个核苷酸的缓激肽合成基因所取代,而不影响翻译框架。在对该病毒敏感的CV-1培养细胞上测试了SV 40(Brd)的生物活性。采用免疫荧光法检测T抗原并检查该重组体的细胞病变作用。基因工程设计并未使该重组体丧失野生病毒典型的生物学特性。
