Description

• 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.
• Application: Glycogen from Mytilus genus (Blue mussel) has been usedas a coprecipitant in the isolation of RNA from hepatocytes[1] and yeast cells.[2] as a reference standard in calibration curve generation to quantify hepatic glycogen content.[3]as a carrier molecule for DNA and RNA, replacing tRNA or sonicated DNAfor the precipitation of DNA in the presence of ammonium acetate and ethanol or isopropanolfor recovery of tRNA, yeast RNA, sonicated DNA and oligonucleotides as short as 8 base pairs
• Biochem/physiol Actions: Glycogen levels in Mytilus genus shows variation during seasonal changes.[4] It is a crucial stored energy reserve for Mussels and is utilized during gametogenesis.[5] Glycogen levels dictate the reproductive capacity and development of mussels larva.[5] Glycogen aids in the coprecipitation of nucleic acids during isolation and purification.[1]
• Features and Benefits: product provided is 1 mL total volumeprecipitates even small amounts of DNA and RNA present in dilute solutionsdoes not interfere with OD 260/280 readings
• Principle: 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.
