title: [Preparation of giant RNA from bovine thyroid gland by agarose gel filtration].
abstract: Giant RNA's were prepared by a rapid gel-filtration technique. DNAase, pronase and thyroid homogenate were successively placed on the column. Proteins and DNA were degraded during filtration. Void volume contained pure giant RNA's. Giant RNAs' yield was 7 times higher with this method than with phenol method.
