Description: 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.

Description: An excellent reagent for maintaining SH groups in reduced state; quantitatively reduces disulfides. DTT is effective in sample buffers for reducing protein disulfide bonds prior to SDS-PAGE. DTT can also be used for reducing the disulfide bridge of the cross-linker N,N′-bis(acryloyl)cystamine to break apart the matrix of a polyacrylamide gel. DTT is less pungent and is less toxic than 2-mercaptoethanol. Typically, a seven fold lower concentration of DTT (100 mM) is needed than is used for 2-mercaptoethanol (5% v/v, 700 mM).

Description: 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
