VWR®, Nucleic acid loading dyes

Supplier: VWR Chemicals

Designed to optimise loading nucleic acids in agarose gels, the loading dye imparts colour to the sample to facilitate the loading process and increase the density of the sample to ensure efficient sample distribution into each well. The dye migrates independently from the sample, allowing estimation of the migration of nucleic acids.

VWR® Real Time Electrophoresis Systems

Supplier: VWR Collection

VWR® Real Time electrophoresis systems have revolutionised DNA electrophoresis. it is no longer necessary to remove a gel from a tank, place it onto a transilluminator for viewing or place the gel into an imaging system to take a photo. These versatile and compact systems are an all-in-one replacement for a power supply, gel tank, transilluminator and gel imaging system.

Urea 8 mol/l in aqueous solution, Proteomics Grade

Supplier: VWR Chemicals

A convenient pre-mixed solution that is easily diluted for buffer preparation under denaturing conditions.Commonly used to denature nucleic acids for electrophoresis and to study the secondary and tertiary structure of proteins. Effective for maintaining DNA in a highly denatured state during sequencing protocols, urea is also useful for accelerating the activity of Proteinase K digestions.

Agarose, Electran, high resolution for electrophoresis

Supplier: VWR Chemicals

Agarose high resolution (HR) has melting, max. 90 °C, and gelling temperatures (32,5 to 38 °C), but differs from traditional low melting point molecular biology grade agaroses in the gel separation range. Using this agarose in electrophoresis allows fine and consistent resolution of nucleic acids below 1000 base pairs, which differ by only a few base pairs. The properties of Agarose HR allow consistent gel separations (analytical and preparative) and performance of in-vitro translation and transcription mapping, as well as in-vivo ligation and transformation. For analytical gel separation of DNA/RNA below 1000 base pairs, where a higher gel strength for ease of manipulation is required, we recommend the use of Agarose, high resolution, Electran (43655).

Magnesium sulphate, anhydrous ≥99%, powder, BAKER ANALYZED®, J.T.Baker®

Supplier: Avantor

The USP/NF Offical Compendia of Standards contains a section titled, "Reagents, Indicators, and Solutions" that lists the quality requirements of chemicals to be used in compendia testing. PharmaTest reagents are tested according to these requirements, relieving you of the need to do additional testing on your reagents. Products may be reagent or other grade, but are labeled as "Meets reagent specifications for testing USP/NF monographs." Test solutions are labeled as PharmaTest.
