Abstract

A novel method has been devised to extract poly (A+)RNA from seed tissues. The advantages of this technique include the speed of extraction and the elimination of the hazardous phenol:chloroform extraction step which usually precedes oligo (dT)-cellulose column chromatography. Instead, the crude supernatant, containing a high concentration of SDS and salts to effectively inhibit RNase activity, is passed directly over the oligo (dT)-cellulose column. The resultant isolated poly (A+)RNA is of high yield and purity and is suitable for in vitro translation and Northern blot analysis.
