301 Results for: "VWR"

Supplier: VWR

VWR® electrophoresis gel loading dyes are tested for contaminating DNase, RNase, and protease activity and are sterile filtered for long shelf life and stability. In addition, all dyes are function tested and do not interfere with sample migration. Their ready-to-use format eliminates exposure to potentially irritating and harmful powdered dyes. Agarose Gel Loading Dye is designed to optimize loading nucleic acids in acrylamide and agarose gels by imparting color to the sample to ensure efficient sample distribution into each well. Its blend of three tracking dyes make estimating sample migration simple and reliable.

Ethidium Bromide solution is a fluorescent stain for visualizing nucleic acids in solution or in electrophoresis gels. At a concentration of 0.5 µg/ml, ethidium bromide is useful in agarose or acrylamide ges for band detection. It is used to detect as little as 10 ng of nucleic acid. At high concentrations (0.5 - 1.0 µg/ml), it may be used to facilitate purification of DNA in cesium chloride gradient.

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).

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.

AMRESCO’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
