High-Efficiency Carrier for Nucleic Acid Precipitation in Molecular Biology Applications
Thermo Scientific™ Glycogen (Molecular Biology Grade) is a highly purified, inert polysaccharide derived from oysters, designed to significantly enhance the recovery of nucleic acids—including low-abundance DNA and RNA—during alcohol precipitation. Its strong precipitation-enhancing capability makes it an ideal choice for workflows involving dilute or low-yield nucleic acid samples, such as those encountered in cloning, PCR, or sequencing protocols.
Unlike other carriers such as tRNA or polyacrylamide, glycogen forms a clearly visible pellet, simplifying recovery and reducing sample loss. It is non-inhibitory to enzymatic reactions and compatible with common downstream processes like PCR, ligation, DNA sequencing, and in vitro transcription.
Key Features & Benefits
- High-Efficiency Nucleic Acid Carrier – Recovers DNA/RNA from as little as 20 pg or oligonucleotides longer than 8 bases
- Visible Pellet Formation – Glycogen forms a precipitate upon ethanol addition, enhancing pellet visibility during centrifugation
- Non-Interfering – Inert carrier that does not affect enzymatic reactions or spectrophotometric readings (A260/280)
- Molecular Biology Grade – Optimized for DNA recovery, suitable for cloning, transformation, PCR, and more
- Superior to tRNA or Polyacrylamide – Offers higher recovery efficiency in ethanol precipitation protocols
Applications
- Ethanol or Isopropanol Precipitation of DNA – Improves recovery from low-concentration or dilute samples
- RNA Purification and Cleanup – For DNA-grade glycogen use only (#R0561); RNA-grade available separately (#R0551)
- Cloning & PCR Workflows – Recovers low-concentration PCR products or cloning fragments
- DNA/RNA Labeling & Enzymatic Reactions – Compatible with ligation, endonuclease digestion, cDNA synthesis
- Bacterial Transformation & In Vitro Transfection – Enhances nucleic acid handling with no adverse effects
