Glycogen is an inert carrier that increases the recovery of nucleic acids after alcohol precipitation. Insoluble in ethanol or isoproanol, glycogen traps the nucleic acids during precipitation and forms a visible pellet upon centrifugation. As an inert co-precipitant, glycogen efficiently recovers from dilute solutions DNA or RNA molecules ranging in size from small oligonucleotides to megabase molecules.

Glycogen solution is an inert carrier used to increase nucleic acid recovery from alcohol precipitation. It is a preferred co-precipitant for solutions containing oligonucleotides or low concentrations of DNA or RNA, as it does not add exogenous nucleic acids like other co-precipitants, such as yeast RNA or tRNA. Glycogen, a highly purified branched chain carbohydrate ,is insoluble in ethanol and isopropanol and forms a precipitate that traps nucleic acids.Upon centrifugation,the insoluble glycogen/nucleic acid precipitate forms a visible pellet that simplifies downstream sample processing. Glycogen Solution, 20mg/mL is free of host DNA and is functionally tested for DNA precipitation. It will not affect the OD260/280 ratio or determination of nucleic acid concentration.
