Loading dyes are designed to optimise loading DNA, RNA, and proteins in acrylamide and agarose gels.
- Protease tested
- Functionally and analytically tested to ensure consistency and quality
- Used for denaturing protein electrophoresis
Ready to use format eliminates exposure to irritating and potentially harmful powdered dyes. All VWR loading dyes feature our exclusive blend of three tracking dyes that make estimating sample migration simple and reliable.
Dye #1: A light blue dye that migrates at 4000 base pairs in 1% agarose
Dye #2: An indigo dye that migrates at about 600 base pairs in 1% agarose
Dye #3: A magenta dye that migrates at 150 base pairs in 1% agarose
Contains 2% SDS and 10% glycerol for denaturing gel sample preparation.
Loading dyes serve three functions in electrophoresis. First, dyes impart colour to the sample to facilitate the loading process. Second, loading dyes increase the density of the sample to ensure efficient sample distribution into each well. Third, the dyes themselves migrate independently from the samples, allowing the user to estimate the migration of nucleic acids or proteins.
