A method of HPRE synthesis via transcription by T7 RNA polymerase in vitro / 中华肝脏病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To synthesize highly pure HBV post-transcriptional regulatory element (HPRE) via transcription in vitro by T7 RNA polymerase.</p><p><b>METHODS</b>HPRE gene was amplified by PCR from a template containing HBV complete genomic DNA and cloned into plasmid pGEM-11zf. The cloned DNA sequence was transcribed by T7 RNA polymerase.</p><p><b>RESULTS</b>The construction of HPRE gene recombinant plasmid and production of HPRE via transcription in vitro was successful.</p><p><b>CONCLUSION</b>In vitro transcription by T7 RNA polymerase can be used to synthesize highly pure HPRE.</p>
