Ribonuclease A is an endoribonuclease that efficiently hydrolyzes RNA contaminants in DNA preparations from tissue or bacterial cell cultures. RNase A is used for a variety of molecular biology applications, most commonly for the hydrolysis of RNA that contaminates DNA preparations. This enzyme is used during plasmid purification without nicking or degrading plasmid.

Supplier: VWR

VWR’s molecular biology grade glycogen is an inert carrier that increases the recovery of nucleic acids after alcohol precipitation. Insoluble in ethanol or isoproanol, glycogen traps the nucleic acids during precipitation and forms a visible pellet upon centrifugation. As an inert co-precipitant, glycogen efficiently recovers from dilute solutions DNA or RNA molecules ranging in size from small oligonucleotides to megabase molecules
