This preparation is used as a carrier for the precipitation of nucleic acids (DNA or RNA). As an inert material it may replace tRNAs or sonicated DNAs.
20 μg glycogen (1 μl solution) allow to precipitate pg-amounts of DNA or RNA from a volume of 1 ml.
In a typical experiment 5 pg [3H]-labeled calf thymus DNA were dissolved in 500 μl 10 mM Tris-HCl, pH 8.0; 1 mM EDTA; 0.4 M LiCl. 1μl glycogen solution (20 μg glycogen) as carrier was added and then precipitated with 1.2 ml ethanol at -15 to -25 °C and stored for 3 hours at -15 to -25 °C. After centrifugation (10 minutes at 12 000 × g) the total radioactivity was found in the precipitate. Without addition of glycogen no precipitation of DNA occured.
