The exact composition of Glycogen Solution is confidential. The Glycogen concentration is 20mg/mL. Glycogen Solution is a component of Gentra Puregene Kits for DNA purification. During isopropanol precipitation, Glycogen Solution acts as a nucleic acid carrier and helps to efficiently precipitate small amounts of DNA. In addition, it facilitates visualization of the DNA pellet. Glycogen Solution can be purchased separately.
Note: Glycogen Solution does not work in combination with QIAGEN’s silica membrane technologies, e.g., RNeasy, DNeasy, QIAamp, etc. With these technologies, poly-A carrier RNA is used when dealing with low amounts of nucleic acids.
