Competitive DNA-RNA Hybridization of Microsomal and Nuclear RNA in Normal Tissues of the Rat¹ Available to Purchase

Purified nuclear and microsomal RNA from rat brain, spleen, kidney, and liver were compared by means of competitive DNA-RNA hybridization. In the experiments described in this report a close similarity in the sequences detected by this technique is noted in the nuclear RNA of kidney, brain, and liver, while a portion of these sequences appear to be missing from the nuclear RNA of spleen. Microsomal RNA from each of the four tissues appears to be qualitatively different.
