title: [Use of a histological fixative for extraction of the RNA precursor pool from mollusk nerve tissue].
abstract: The incorporation of 3H-uridine into the nucleotide pool of the molluscan nerve tissue was calculated in a routine fixative solution (formalin--alcohol--acetic acid, 9:3:1). The optimal conditions for the precursor output from the tissue being studied, the results obtained well compare with those obtained by common biochemical techniques. Our method gives a possibility to use the same sample of tissue for historadiographical investigation of labeled RNA and for cytochemical determination of nuclear acid amounts.
