Glycogen is an inert carrier that traps nucleic acids. It forms a precipitate with DNA/RNA while being insoluble in ethanol solution. Due to the manufacturing process, there is low risk of contaminating nucleic acids in the glycogen. This product is tested for DNase, RNase, and NICKase, but not nucleic acids.


Suitable for
• precipitation of DNA in the presence of ammonium acetate and ethanol or isopropanol
• recovery of tRNA, yeast RNA, sonicated DNA and oligonucleotides as short as 8 base pairs

Features and Benefits

• product provided is 1 mL total volume
• precipitates even small amounts of DNA and RNA present in dilute solutions
• does not interfere with OD 260/280 readings

General description

Glycogen is a branched polymer of glucose synthesized by animal cells for energy storage and release. It is constructed of predominantly α1→4 glycosidic bonds with branches created through α1→6 glycosidic bonds.

Glycogen is a branched polymer of glucose that coprecipitates nucleic acids during isolation and purification.
