Phenol extraction from seeds is dependent, in part, on the degree of seed oxidation or maturity.
It has been reported that the use of soluble polyvinylpyrrolidone for RNA extraction without ultracentrifugation is suitable for eliminating proteins during RNA isolation, although polyvinylpyrrolidone interferes with phenol extraction (Woodhead et al., 1997; Salzman et al., 1999).
Table 5 also shows that the maximum phenol extraction recovery was reached using methanol, followed by ethanol (more than 90% for both solvents) and acetone.
Figure 1 shows the results of three phenol extraction procedures (Lanes 1-4), a detergent-potassium acetate method (Lanes 5 and 6), phenol:chloroform: isoamyl extractions (Lanes 7 and 8), as well as protoplast preparation (Lane 9) and processing in agarose plugs (Lane 10).
