枸杞果实总RNA提取方法的比较研究

扫码查看
以枸杞果实为植物材料,比较研究Trizol试剂快速提取法、异硫氰酸胍法、TransZol plant试剂盒法、CTAB法和改良CTAB法提取枸杞果实RNA的可行性.结果表明,改良CTAB法能有效地抑制酚类物质、多糖及皂苷等次级代谢产物对RNA的影响,可从枸杞果实获得质量高、完整性好的总RNA;RT-PCR分析显示提取的总RNA具有反转录活性;该方法具有高效、简单和经济的特点.
Comparison for the Extraction of the Total RNA from Lycium barbarum L.fruits
The performances of the five extraction of the total RNA, the Trizol, the guanidinium isothiocyanate, the CTAB, the TransZol plant kit and the improved CTAB from Lycium barbarum L. Fruits tissue that is rich in polysaccharides polyhenolics and the pigments are compared in this paper. The yields,the quality and the integrity of RNA are tested by ultraviolet spectrophotometer analysis(A260/280) and 1. 0% agarose gel electrophoresis. The RNA can be used for reverse transcription and PCR amplification efficiently. Therefore,the improved CTAB extraction would be the fast and the efficient for the total RNA isolation from Lycium barbarum L. Fruits.
