HowtoprepareMolecularBiologygradeglycogen
OverviewGlycogen can conveniently substitute for tRNA as a carrier for nucleic acid precipitation. Although Molecular Biology grade glycogen can be purchased from a number of vendors, the main disadvantage is that it is very expensive (e.g., About 100 dollars/20-40 mg).Here we present a simple and inexpensive protocol to prepare a large amount of glycogen which is suitable for any kind of Molecular Biology......阅读全文
