Abstract:

In order to construct a long-term and high-level transgene expression recombinant vector,LIAS gene was cloned from the muscle of porcine by RT-PCR and inserted into minicircle plasmid.The minicircle-LIAS vector was transfected into HeLa cells to investigate the duration of GFP expression.The results showed that the LIAS gene which was 1 119 bp length was completely cloned and inserted into minicircle plasmid.The vector was transfected into HeLa cells and the duration of GFP expression of recombinant minicircle-LIAS vector was obviously higher than that of pEGFP-N1 plasmid.This result provides a new thought and experimental material for the process of LIAS biological synthesis and function regulation.
