Two methods of different RNA extractions from Conus venom tube and toxin gland of seven cone snail species were performed. ThermoScript~ TM RNase H~ - Transcriptase and AMV Transcriptase were used to synthesize cDNA separately.

• 采用不同的RNA提取方法,从7种海南产芋螺的毒管中分离总RNA,用两种反转录酶分别合成cDNA,再以合成的cDNA为模板进行PCR扩增。
