CTAB, Phenol （saturated with water）, chloroform, Guanidine isothioeyanate were used as main extraction reagents. Polyphenolie compounds were removed effectively by added PVP into the extraction buffer solution. RNA was purified intensively by phenol, chloroform extraction, and ethanol deposition after deposited by LiCl. Both the results of formaldehyde denatured agarose gel eleetrophoresis and ultraviolet spectrophotometer analysis showed high integrity and purity of RNA. So the quality of extracted RNA could meet the demand of most molecular biology experiments that require higher quality RNA.展开更多
