[The creation of an SV40 virus-based vector as an experimental model for the study of gene expression]

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.
